IDE Hard Drive
Interface
The L6-bit IDE hard drive interface,P10,is a standard 40-pin connector.This interface
supports 16-bit data transfersin a single cycle.P10can be connectedto the CM104 1.8inch
hard drive utilityModulerM or to any other 16-bit IDE hard drive.
Floppy Drive
Interface
The high density floppy drive interface,P8, is a 34-pin connectorwhich supports two
high density floppy drives (360K 720K,1".2MB,or 1.44MB)configured as disk drives A: and
B:. Note that eachof the two PCMCIA cards supported by the system are also accessedas
disk drives A: and B:. Therefore,the systemcan support a combined total of two floppy
drives or PCMCIA cards.
PCMCIA
Interface
The P2 PCMCIA interface,included on the CMF8680-2module, is a 32-pin connector
which mates to the CM102 PCMCIA utilityModule. This 32-pin auxiliary bus stacksdirectly
with the CM102 utilityModule, requiring no additional external cabling. SRAM cards,ROM
cards,and EPROM cards which adhereto the PC Memory Card Intemational Association
Release1.0standard can use this interface.Memory cards of up to 32 MB can be read and
written (SRAM only) through this interface.
Keypad
Scanning
The CM102 utilityModule adds X-Y matrix keypad scanningwhich is supported in the
CMF8680BIOS.The keypad layout is user programmable,and the keypad can be used with
or without a standard XT keyboard.
CGA CRT/LCD
Graphics
Controller
The CGA CRT/LCD graphics controller, P7, is a 10-pin connectorwhich interfacesto
most popular CGA and LCD flat panel displays. This interfacesupports 80 x 25 and 40 x 25
text modes, as well as 640 x 200pixel 2-coIor,320x200 pixel 4-color, and 640x 400 double
scangraphics modes.\Alhendriving a CRT or LCD panel, the CGA graphics controller
displays colors or up to 16 shadesof grey.
1-5
RS-232Ports
Two 16450compatible RS-232serial ports, P11 and P9,provide support for user peripherals such as a mouse or modem. P11is from the F8680CPU chip and can be programmed as
COM1, COM2, or disabled.P9 is from theS2CT2Lcontroller chip and can be programmed as
COML, COM2, COM3, COM4, or disabled.Both serial ports operateat up to 115Kbaud.
RS-485Port
The RS-485serial port, P5, supports multidrop systemconfigurations where several
devicesare controlled through a single port. It can be programmed as COM1, COMZ, COM3,
or COM4. \A/henusing P5, you must configure the associatedjumper on header cormector
P14so that the line is terminated or not terminated. The RS-485path must be terminated at
both ends for proper operation. If the CMF8680is at the end of the path, then install the
jumper atPL4 to terminate the line. If the CMF8680is located somewherein the middle of the
R$485 path, remove the jumper at P14so that the line is not terminated. Asserting the RTS
signal on the serial port enablesthe RS-485driver. The RS-485receiver is always enabled.The
RS-485usesa 16450compatible UART.
Parallel
Port
Utilitv Port
This port, P6, can be programmed as aPC/ AT enhancedbidirectional parallel port or as
a standard printer port and can be program.medat address3BCH, 378H, or 278H, or disabled. The parallel port cable should be lessthan 10 feet long to ensure reliable data transfer.
The 10-pin utility port,P4, provides XT keyboard signals,piezoelectricspeakersignals,
system reset,suspend,/resumeswitch signal, sleepmode monitor, and battery backup
connections.The pin assignmentsare given below. The speakersignal can drive an external
piezoelectricspeaker.\Atrhenthe RESETline is taken low at pin 3, a systemreset occurs.Pin 4,
PWRUP, is used to place the systemin and out of the suspendmode for power conservation.
\A/henconnectedto a slide switch, a high keepsthe system in the run mode and a low places
it in the suspendmode. \A/henconnectedto a pushbutton switch, the mode togglesbetween
run and suspend eachtime the switch is depressed.The switch type is user configurable
using RTDMOD.EXE (seeChapter 3, Power ManagementSetup discussion,for more details).
Note that the PWRUP signal must be properly debounced.An XT keyboard with a standard
S-pin DIN connectoris connectedto pins 5 through 8. A normally open reset switch can be
connectedbetween pins 3 and GND. A battery to back up the real-time clock can be connected between pins 9 and GND. Pin 10 is low when the cpuModule is in the suspend mode.

CHAPTER 2
Installation
2-1,
This chapter describes the installation procedures for integrating the CMF8680 into a
PC/104 system.
STACKING
MODULES
The CMF8680can be stackedwith other PC/1,04form factor modules to form a cubical
system,as shown Figure 2-1.\,Vhenstacking the CMF8680,first make all of your peripheral
connections.Be sure to connectpin L of the cable to pin L of the corurector.The connectorsare
labeled on the board. If you cannot read the label, pin L can be identified by its square solder
pad, visible on the top and bottom sidesof the module.
After all peripheral connectionsare made, insert the pins of the PC/104 expansionbus of
one module into the socketson the secondmodule, making sure the pins are properly
aligned before seatingthem into the sockets.The order of the modules in the stack is not
important as long as all modules in the middle have a stackthrough PC/104 bus connector.
After the modules are stacked,insert the spacersprovided with eachmodule to securethe
stack.Figure 2-2 shows a typical stack.The stack is now ready to install in your system.
NOTE: Sincemost dataModules do not have the extra 32-pn auxiliary bus connector,we
recommend that, if you have the -2 version of the CMF8680with the optional P@PCMCIA
connector,you place dataModules on top of the CMF8680and utilityModules under the
CMF8680,as shown in Figure 2-2.

CHAPTER 3
Start Up
3-2
This chapter tells you how to use the configuration setup program, RTDMOD.EXE, and
how to start up your CMF8580.Systemboot options, the BIOS and SupterStateR" and the
watchdog timer are also discussedin the chapter.The settingsshown in the manual are the
default settings.
RTDMOD
SETUP
pROGRAM
The system configuration program/ RTDMOD.EXE,is used to set up the various parameters of the CMF8680before you boot the system.The setup program is on a utility disk
shipped with your CMF8680.To run the setup program/ you will need a CRT, keyboard, and
floppy drive. The setup program can be placed in a ROM disk, or on the hard drive, if
desired.
The first screenin the RTDMOD setup program is shown in Figure 3-1.When the program starts, it loads the settingsfrom the configuration EEPROMto ensurethat you are
is proworking with the actual systemconfiguration. A default setting, RTDDFLTO.SET,
vided. If you should get into trouble when configuring your system,such as turning off the
CRT display, you can hard resetthe systemand simultaneously hold down both <Shift> keys
and the system will boot using the default settingsin the BIOS.The RTD utility ROM disk
must be installed in the user EPROM socket.The default settings are:
Drive A: 5-114inch 1.2Mfloppy
Drive B: PCMCIA
IDE disabled
ROM-DOS enabled
CGA graphics on a CRT
The main page lets you load the current settings,savethe new settings,and then exit the
program or abort the new setup. The current settingscan be loaded from the EEPROM,the
default file, or from a user file. Settingscan be saved to any one of thesethree locations.The
abort/exit menu lets you revert to the last saved configuration, exit with a hard reset (a hard
reset is necessaryto implement most con{iguration changes),or exit to DOS without making
any changes.The HELP menu is also shown in Figure 3-1 at the bottom of the screen.In
addition to the keystrokesdescribedin HELP, ESCwill send you back to the Main Page.

Figure 3-12configures the intemal graphics controller. Rememberthat if you disable the
controller, you will not have CGA graphics and you must make sure that you have another
display device (e.9.,VGA card and monitor). When using a standard VGA board with the
CMF8680,it is not necessaryto disablethe CGA graphics;however, most VGA boards will
try to emulate the CGA modes, and this could causeproblems.

Power managementoptions are shown in Figure 3-19.The PWRUP switch type and
polarity are set here according to the switch connectedto utility connectorP4, pin 4. Refer to
Chapter 4 for more information about power management.\Alhilethere are many possible
combinations of switch type and mode of operation of the PWRUP signal, the following
paragraphs describesomeways you can implement this feature.We will look at slide and
momentary switch operation to describethe basic function of the PWRUP signal.
NOTE: It is very important that any switch connectedto the PWRUP signal
be properly debounced.
Slide Switch Operation: \A/henthe PWRUP signal is high, the CMF8680is running, and
when PWRUP is low, it is in the suspendmode. To implement this configuration, use
RTDMOD.EXE to set the PowerUp Switch Type to Slide and the PowerUp Switch Polarity to
Switchon PWRUPgoingHigh. The switch you connectto the PWRUP signal can be a slide
switch that is open in one position and grounded in the other position (PWRUPis intemally
pulled up on the CMF8680).When the switch is open, the CMF8680will run, and when it is
grounded, the CMF8680will be in the suspendmode. A normally open momentary pushbutton switch can also be used in this configuration. When the button is released,the
CMF8680is running, and when it is pressed,the CMF8680entersthe suspend mode.
Momentary Switch Operation: This mode requires that you use a normally closed pushbutton switch connectedto the PWRUP signal. PWRUP should be low for normal operation.
\A/henPWRUP is brought high and then back to low, the CMF8680enterssuspend mode.
When PWRUP goeshigh and then low a secondtime, the CMF8680resumesrunning. To
implement this configuration, use RTDMOD.EXEto set the PowerUp Switch Type to Momentary and the PowerUp Switch Polarity to Switchon PWRUPgoingLow.
If you do not use the PWRUP signal, set the PowerUp Switch Polarity to Disabled.

Figure 3-28shows the screenwhere you program the values for your keypad matrix
when you are using the keypad scanningfeature of the CM102 utilityModule with the
CMF8680.Depending on the number of rows by columns you configured on the screen
shown in Figure 3-26, all or part of this table will be used to enter the scancodes.The portion
of the table where the scancodesare to be entered is highlighted. For example,supposeyou
select a matrix size smaller than 16 rows by 8 columns, such as 4 rows by 2 columns. The
table in Figure 3-28will have the last eight words highlighted to enter your scancodes.\A/hen
your matrix is smaller than the full table, the data words used to enter scancodesare always
highlighted from somepoint within the table to the end. This allows unused memory to be
free for other functions.
When you enter data, the first word (going from top to bottom and left to right) corresponds to row 1, column 1 on the keypad; the secondword correspondsto row 1, column 2;
and so on. Eachword in the table programs two keys: the low byte programs the scancode
for the keystroke when the Fn (or Ctrl + Alt) key is NOT depressed;the high byte programs
the scancode for the keystroke when the Fn key IS depressed.Note that in order to activate
the Fn key feature, at some location in the table, you must define both the low and high bytes
of the SAME WORD with the Fn key scancode.The scancodesare defined in Chapter 6.
Refer to this chapter for complete information on programming scancodes.

SuperStateR is a combination of specialsoftware instructions and internal PC/CHIPTM
hardware that extend the processorcore/ allowing additional featuresto be supported
transparently to normal DOS and BIOSoperation, without the need for complex hardware.
SuperStateprovides:
- Control over hardware extensionswithin the PCICHIPTM
Five programmable pins that are used to:
provide the PCMCIA card R/W detect.
provide LCD signals.
allow watchdog timer control.
Power control logic which allows the chip to be powered-up by internal timer
activity or hardware switch and powered-down by software.
Memory accesscontroller registerswhich generatethe appropriate cyclesfor
ROM, dynamic RAM, PCMCIA cards,and the PCl104 bus.
Performancecontrol registerswhich allow CPU waits between instruction
executionto be adjusted to reduce systempower consumption.
- Memory Management,which allows up to 64 MB of memory to be addressedthrough a
64KB mapping system,which in this design can reach the combination of ROM
(1.25MB), RAM (2 MB), and two PCMCIA devices(32MB each).This control also
allows the following'user' featureswithout additional hardware:
3-20
EMM driver which provides support for the LIM EMS 4.0 standard, that allows the
DOS programmer to reachmemorybeyond the 1 MB addressingspaceof the 8086
classprocessor.
HIDOS device driver which allows DOS to be loaded in HMA memory space
(memory above the 1 MB addressspace).
ROMDISK accessfor ROM-DOS and user EPROMbased disk emulation.
- Virtual I/Ciru and Virtual lnterruptsrM,which allow for the emulation of floppy disk
hardware to support PCMCIA disks that act like floppy diskettesto software that does
direct hardware accessand control. Thesefeaturesare also used to accessIDE hard
disks.
WATCHDOG

The CMF8680has a hardware watchdog timer that is user controllable. lvVhenenabled,
the watchdog timer must be resetevery 1.6secondsor it will perform a hardware reset on the
CMF8680.SeeApplication Note CMF8580-1,Using theCMF8680WatchdogTimer, in Appendix D for detailed operation and exampleprograms.
The system switchesto extemal battery backup from utility connectorP4-9to maintain
the real-time clock when power is switched off. If maintaining the date and time while the
system is off is not required, the battery can be omitted. All systemconfiguration parameters
are saved in the non-volatile serial EEPROM.
HIDOS.SYSis a device driver for the PCICHIP that allows MS-DOS5.00to be loaded in
HMA (memory above 1 megabyte).The following two lines should be added to the
CONFIG.SYSfile:
DEVTCE = HTDOS.SYS
DOS = HIGH
EXPANDED
MEMORY
This section describes the MS-DOS device driver PCCEMM.SYS, which, in conjunction
with a Chips and Technologies F8680 PCICHIP, provides support for LIM EMS 4.0.
This EMS driver is supplied as a device driver that can be loaded at DOS boot time. The
user is required to edit the CONFIG.SYS file so that it contains a line in the form of:
D E V I C E = d : [ p a t h ] \ P C C E ] . O { . S Y SI o p t i o n s ]
where d: and [path] represent the drive and path where the driver is located.
The driver is designed so that, under normal circumstances, it does not need any command line options in order to give satisfactory performance. Flowever, command line options
are provided so that the driver may be tailored to a user's specific needs.
Before installing the driver, you should run your system SETUP and make sure to set
aside sufficient memory for your needs. This memory should be designated as expanded
memory.

Command Line
parameters
The following command line parametersare available for knowledgeableusers who wish
to tailor the driver for their own requirements.Option namesmay be shortened to their first
two characters.Options should be separatedby one or more spaces.Spacesare optional
beforeand after the'-' and'=' symbols.
HANDLES = hhh

aaacan be 208,218,258,268,248,2B,8,
DIAGS = xxx
Specifieswhether EMS memory diagnosticsare performed during initialization of the
driver. "xxx" must be ON or OFF.The default is OFF.
SIZE = ssss
Specifieshow much of the RAM above 1M should be used for EMS memory. If there is
no XMS driver in the system,then the default for the EMS driver is to use as much memory
as is available.If there is an XMS driver in the system,then the EMS driver will default to
using 256K for EMS. Thesedefaults may be overridden by using this option. ssssis specified
in k's and mustbe a multiple of 64k.
Error Messages
"Initialization Error. Memory Managernot Installed"
This is a generic error messagethat is accompanied by another error message.This
means that for somereason(given by the other error message)the EMM driver could not be
installed correcfly.
"Cannot detect mapping hardware"
The EMM driver could not find a F8680PCICHIP in the system.Make sure that your
EMS is enabled.This error may indicate that you have the wrong driver for your system.
"Problems encountered with memory initialization"
The EMM driver could not set up the page frame correctly. Make sure that there is a
contiguous 64K segmentof unused memory spaceat D000.
"Interrupt 67 Vector already allocated"
Someother driver has already allocatedthe EMS interrupt vector. Remove all other EMS
drivers from your CONFIG.SYSfile.
"VO addressspecified is not one of the permitted values"
The EMS mapper I/O addressyou indicated using the IOADDR command line option is
an invalid address.Make sure that it is 208.
"An equals (=) sign was expected"
One of your PCCEMM.SYScommand line options was not immediately followed by an
equals '='sign. Check your CONFIG.SYSfile to make sure the PCCEMM.SYScommand line
is formatted correctly.
"Number of handles invalid or out range"
The value you specifiedfor the HANDLES command line option is invalid. Make sure it
is a decimal number between L6 and 255.
3-22
"No working memory can be found. EMM aborted"
The driver cannot find any memory set aside as expandedmemory. Make sure to run
your system SEruP, and set aside somememory for expanded memory.
"Unrecognizedcommand./optionin commandline"
The string displayed after this error messagewas found to be invalid. Edit your
CONFIG.SYSto make sure this invalid option is corrected.
"The command line is incomplete"
Options are incomplete on the PCCEMM.SYScommand line. Make sure that all command line options are correctly formatted.
"Problems encountered in setting default page frame address"
The default page fuameaddress(D000)is invalid. Make sure that no other driver is using
this area of memory.
"Decimal number input overflow error"
The number of handles specified is an invalid number. Edit your CONFIG.SYSand make
sure that the parameter for HANDLES is correctly formatted.
"Error EMS I/O not enabled"
EMS has not been enabled on the Chips F8680PC/CHIP. Run your system SETUPand
make sure EMS has been enabled.
"The EMS hardware is disabled or not functional"

TRANSFER
PROGRAM
TRANSFERis a file exchangeutility that allows embedded systemsto upload and
download files over a serial link. TRANSFERusesBIOScalls to send and receivebytes. This
allows TRANSFERto operateon any systemwith a BIOS.
TRANSFERexecuteson a target system.The program running on the host systemmay
be either COMM, the serial communicationsutility, or another copy of TRANSFER.
TRANSFERmay be used to transfer files via the console,assuming that the consoleis
implemented via a serial port. In this case,TRANSFERusesBIOS interrupts 10H function E,
and 16H function 0.
The TRANSFERprotocol used by both COMM and the TRANSFERprogram is referred
to as Xmodem by the communicationscommunity.
In order to move a file between systems,run TRANSFERon the target system.Either
TRANSFERor COMM may be run on the host PC. If COMM is rurming on the host PC, press
the PgUp key on the PC to tell COMM to send a file to the target system.COMM will prompt
for the file name and the protocol for TRANSFER.Specify the Xmodem protocol. If you are
using TRANSFERon the host, selectthe COM port, the baud rate, and specify either send or
receive.
TRANSFERis run as follows:
A : > T R A N S F E R{ O p t r o n s }
FileName
3-23
The options to TRANSFERstart with a slash (/) and are followed with a letter. These
options tailor the operationsof TRANSFER.The FileNameargument specifiesthe file to be
uploaded or downloaded. A path and a drive may precedethe actual file name. Wildcards
are not allowed in the FlleNameargtrnent.
The /Brate option allows the user to set the baud rate. The ratenumber may be 300,1200,
57600,or L15200.This causesthe TRANSFERto use a COM1,
2400,4800,9600,19200,38400,
whether or not the /COM is specified.The default baud rate is 9600.
The /COM# option causesTRANSFERnot to use the consoleand allows the user to set
the COM port. The COM number (#) may be either 1.or 2. This option causesTRANSFERto
use the serial port BIOS interrupt 14.
The /R option causesTRANSFERto receivea file.
The /S option causesTRANSFERto send a file.
Examples:
A:>transfer /r B:file.dat
This example causesTRANSFERto receivea file via the console.The data of the file will
be placed on drive B: in a file namedfile.dat.
A : > L r a n s f e r / s / 8 1 2 0 0 / C O M 1j u n k . a b c
This example causesTRANSFERto send the file junk.abcover COM1 at 1200baud.
Example:
Target
A : > T R A N S F E R/ r
Host
System Command
B:VI .EXE
PC System Command
A : > T R A N S F E R/ S C : \ B I N \ E D . E X E
This example shows using TRANSFER on both the host PC and the target system. The
file ED.EXE is being sent from the host PC to the target system. The file received on the target
system will be called VI.EXE.
COMM
PROGRAM
Command Line
Options
The COMM communicationsprogram provides the ability to communicatewith the
remote ROM-DOS system.Using COMM, you may also communicatewith the Datalight
BBS.COMM supports Xmodem file transfer,autodialing, and simple terminal emulation.
All command line options must be separatedby a space.
/B#
Set the baud rate to # on startup. The availablebaud rates are
300,1200,2400,4800,96AA,79200,3U00, 5760A,and 775200.
/coM.#
Setthe communicationsport to #. COML and COM2 are suPported.
/SN1
Set the serial port to 8 data bits, no paity, L stop bit.
/7F1
Set the serial port to 7 data bits, even patity, L stop bit.
No other parametersfor data bits besides8N1 and 7EL arecurrently supported.
3-24
Environment
Variable
An environment variable COMM is supported, which may set certain communications
parameters.The switchesare identical to the command line options.
Example:
SET COMM=/COM2 /82400 /]EI
This setsCOMM to start up using COM2, at2400baud, with 7 databits, even parity, and
1 stop bit. If new options are specified on the command line, they override the environment
variable settings.h:rvalidoptions are ignored.
Commands
Most commandsare enteredby pressing an Alt-letter combination. Somecommands take
effect immediately (such as changing the baud rate), while others require further information
(such as a file name) before continuing.
Escis the generalabort key. If you do not wish to executea command, or want to stop a
command while it is going (such as a file transfer),simply press the Esckey and you will be
back in terminal mode.
Terminal
Emulation
AIt-B
Set the baud rate. This command toggles between all the available baud rates. Continue to press Alt-B until the baud rate you
wish appears on the status line.
AIt-C
Clear the screen.
AIt-D
Autodial. This command allows you to type in a number to
autodial;youmay press return to redial the previous one. Esc
aborts the command.
AIt-E
Toggle echo (duplex). Pressing Alt-E will toggle the duplex
between full (echo off) and half (echo on).
AIt-H
Hang up. If the modem is capable of hanging up with an ATHO
command, the line will be disconnected.
AIt-P
Set parameters. This command toggles through the available
parameters. Esc will abort the command.
AIt-T
Toggle CR/LF. When this is enabled, pressing the Enter key will
generate a CR/LF instead of just a CR.
AIt-X
Exit the program. This command does not drop the carrier, so
use this command if you need to do MS-DOS operations while
on-line. You can run COMM again, without losing the carrier,
and continue with telecommunications.
PgUp
Upload a file. This command sends a file to a remote computer,
giving you the option of either Xmodem or ASCII file transfer
protocols. Esc will abort at any time during the transfer.
PgDr
Download a file. This command receives a file using the
Xmodem or ASCII file transfer protocol. Esc will abort at any
time during the transfer.
Currently, COMM automatically supports a subsetof the ANSI Escapecodes.This
emulation cannot be turned off and is the only terminal emulation available.It should,
however, suffice most needssincethe emulation includes such featuresas cursor positioning
and eraseto the end of the line and/ or page.We will not attempt to explain here how the
ANSI Escapecodeswork, but if you understandthem, the codessupportedare A, B, C,D,H,
J, and K.

CHAPTER 4
Power Management
4-2
The CMF8680has sophisticatedpower managementwhich features three power saving
modes: drowse, sleep,and suspend.You can program which modes are active in the configuration setup program, RTDMOD. Suspendcan also be entered using the PWRUP pin on
utility connectorP4 (seeChapter L for connectordescription and Chapter 3, Power Management Setup discussionfor operation using the PWRUP pin). This chapter describeshow these
modes are executed.Table 4-1 summarizesthe power saving feafuresand Figure 4-1 shows
how the power managementis configured.
DROWSE
SLEEP
.
SUSPEND
Drowse usesthe PerformanceControl feature of the F8680CPU to reduce power consumption. PerformanceControl adds delays of 1 to 127 CPUCLK cycles(dummy cycles)
between eachCPU instruction cycle. The CPU and the systemcontinue to run at normal clock
frequency,but the CPU cycle takesplace at a slower rate. The power saving arisesfrom less
over time.
memory and peripheral accesses
The processorentersthe sleepmode by executing a HLT instruction in non-SuperStateR
mode with interrupts enabled.The sleepmode is transparent to the BIOS,DOS, and any
application programs becausetransitions out of sleepmode occur on any enabled hardware
interrupt or Superstatehardware interrupt.
The suspendmode occurswhen the systemis tumed off exceptfor the portions that need
to keep the critical information. The 32 kHz oscillator continues to provide the clock to the
CPU's internal32-bit counter and provides the timing clock for memory refresh.Upon
resume,the OSCPWRsignal is automatically turned on and the systembegins executing
-SLEEPY
signal that is available at the
instructions where it left off (not a systemreset).The
utility connectorP4-10is buffered OSCPWR.

CHAPTER 5
Using the Solid StateDisk
5-1
5-2
BUILDING A
ROM DISK
ROMDISK is a utility for creating a disk file that representsa ROM disk. A ROM disk
contains all the standard parts of a disk that reside on a floppy or hard disk. Each of these
disks contains a boot sector,a File Allocation Table and a root directory, and the files selected
to be included on the disk. The ROMDISK utility supports ROM disks up to 32 Megabytesin
size, sub-directories,and the creation of RXE programs on the ROM disk.
A ROM disk can be used by ROM-DOS for accessingthe user application in a diskless
system. This diskis much the sameas a RAM disk used under DOS, except that it is read-only
and always residesin ROM. The ROMDISK image is built using the ROMDISK.EXEutility
included in your CMF8680utility software package.
Running
ROMDISK
You can run the ROMDISK utility at the DOS command line by typing ROMDISK with
or without parameters.
\Atrhen
it is run without parameters,ROMDISK displays a summary of parametersand
options that looks like this:

The ROMDISK.EXEprogram allows you to produce a ROM diskbinary image or L:rtel
HEX file. This image file is later burned into ROM to createa "ROM disk". The size of the
ROM disk is only limited by the number and size of files placed on the ROM disk and the
1 Megabyte user EPROM.
The ROM disk will have the contentsof a standard disk including a boot recotd, FAT, file
directory and data. The sectorsize,which defaults to \28, may be set by entering the sector
size on the ROMDISK command line. There is no limit to the number of files that may be
placed on a ROM disk.
Placeall of the files to be included on the ROM disk in a directory. Your directory may
contain subdirectories. The main directory that you createwill becomethe root directory on
the ROM disk. All subdirectorieswill remain at their original level. You must use the" /5"
option if you wish to transfer subdirectoriesto the ROM disk. The ROM disk syntax for
<filespec>may include a path.
ROMDISK.EXEis run by typing the program name at the DOS prompt.
This example placesthe contentsof the directory "\trnp", including subdirectories,in the
image file " \ROM-DOS\disk.img".
Example:
/s

The file produced by ROMDISK.EXEdefaults to an image file at address0x000. This file
must be burned into the user's EPROM. The ROM disk must always start at address0000.
ROMDISK
Options
The ROMDISK utility has options to configure its operation. The options are started with
a slash (/) and followed with a letter and possibly a number.
The /E option causesextended recordsnot to be placed in the Intel Hex output. These
records are placed in a Hex file by default.
The /F option allows the user to set the fill bytes. The default is a fill byte of 0xFF. The
number following the /F option is assumedto be in hexadecimalformat.
The /H option causesa Hex file to be produced. The optional number following the /H
option specifiesthe actual addressof the start of the ROM disk. The start addressis required
for ROMable EXE files. The default addressis 0x000.The CMF8680requires all ROM disks to
start at address0x0000,and the user EPROM can contain only one ROM disk.
5-4
The /I option causesan image file to be produced. The optional number following the /I
option specifiesthe actual start addressof the start of the ROM disk. The start addressis
required for ROMable EXE files. The default addressis 0x000.
The /R# specifiesthe RXE interupt number. The default number is 90 Hex.
The /S option causesROM disk to include sub-directoriesfor:nd in the sourcesubdirectory selectedto include on the ROM disk image.
The /T option is the test option. This option causesthe ROMDISK utility to display
statisticson the ROM disk but not to actually createthe image file or hex. This is useful when
you need to make sure that the required files fit in the available space.
The /V "str" option allows you to set the volume label to something other than
"ROMDISK". The volume label string can be up to 11 charactersand must be in quotes.
fhe /Z# optionallowsyoutospecifythesectorsizeoftheROMdisk. Thedefaultsector
size is 128bytes. Legal values for this option are 128,256,and512.
NOTE: /C is not supported. Use an .EXEfile compressionutility if a compresseddisk is
required. To support this, the systemwould not be able to boot from floppy or hard disk and
would use 6K more ROM and 12K more RAM.

The file listed above has the .HEX extensionfor hrtel Hex files. It could iust as easily be
an .IMG binary image file.
ROMDISK.HEX may be anywhere from LK in size to just under 1 Megabyte. A practical
limit is usually lessthan 512K. The ROM disk allows for booting on a completely diskless
system.This file is burned into the EPROM starting at location 0.

The CMF8680-2with the optional CM102 68-pin PCMCIA and keypad scanningconnector supports PCMCIA Release1.0,SRAM, ROM, and EPROM memory cards.Thesecards can
be used with the CMF8680systemin the CM102 utilityModule. Up to two CM102
utilityModules are supported by the CMF8680-2.They operateas floppy drives and are
configurable in the system as drive A: or drive B:. Through the PCMCIA interface,you can
format, read, and write (write to SRAM cards only) PCMCIA memory cards. In addition, the
CMF8680-2and CM102 support up to 16 x 8 X-Y keypads.
This chapter describesthe CM102 and its functions in the CMF8680-basedsystem.

CONNECTION
DIP SWITCH
SETTINGS
The CM102 stacksdirectly onto the CMF8680(seeChapter 1.).
Switch S1,a four-position DIP switch on the CM102 module, must be configured for
correct operation of the CM102.Sections1.through 3 control the PCMCIA selection.Section4
is for keypad enable/disable. Table 4-1 shows the settingsfor switches 1 through 3 on 51.
Make sure you use a valid setting of theseswitches.Note that 0 = CLOSED, and 1= OPEN. If
two CM102's are installed in the system,one must be configured as Drive A:, the other as
Drive B:, and only one module can have the keypad scanningfeature enabled.

Switch S1-4is the keypad enable/disable.When this switch is set to 0 (CLOSED),the
keypad is enabled.When set to 1 (OPEN),the keypad is disabled.
PCMCIA
Like a floppy disk, a blank SRAM PCMCIA card must be formatted prior to use. The
FORMAT.EXE program supplied with the CMF8680 performs this function.
After the card has been formatted, it can be read or written like a floppy. Most PCMCIA
cards have a write protect switch. If the switch is in the write protect position, the system will
not be able to write the card.
\Alhile the system cannot program ROM/Flash EPROM cards, it can read them.
PCMCIA cards can be removed while the system is on without damage to either the
system or the card.

KEYPAD
SCANNING
The F8680chip and the BIOS of the CMF8680provide hardware and software support for
the X-Y keypad scanningfeature on the CM102.You can program up to 16 rows by 8 columns in an X-Y matrix.
The keypad matrix can be any combinationsof rows and columns up to L6 rows by 8
columns, such as the simple 4 x 4 matrix shown in Figure 4-1.\A/henevera key is pressed,a
connectionis made between the column and the row to which the keyswitch is connected.
Column1
Column2
Column3
Column4
Fig.4-1 - Simple4 x 4 KeypadSwitchMatrix
To ensure accuratetranslation of keystrokes,the CMF8680BIOS scansall keys on a
regular basis and transfersthe scancode data to the system.The BIOS performs switch
debouncing and ghost key detection.The BIOS also implements 2-key rollover, where two is
the maximum number of keys that can be pressedsimultaneously on the keypad before it is
not possibleto correctly detect other keys being pressed.Figure 4-2 shows the scanning
algorithm used by the CMFB6B0with the CML02's scanningfeature enabled.

The scancodesare programmed into the 2K bit areaof the EEPROM available to the
user. Programming is done from the systemconfiguration program, RTDMOD.EXE.To use
the keypad scanningfeature, run RTDMOD.EXE,call up the screenshown in Figure 4-3,
enablekeypad scanning,and set up the number of rows and columns you will need for your
keypad matrix. Then, go to the screenshown in Figure 4-4 Nrd enter the scancodesfrom
TabIe4-2 to define the keys. Note that codes01h through 53h are standard XT keyboard
codes.For a 16 x 8 matrix, 128keystrokescan be defined. By defining an Fn key (or Ctrl-Alt)
in one of thesepositions, an additional 128keystrokescan be defined, for a total of 255 keys.
The Fn key is a typical modifier key found on notebooksand palmtops which extendsthe
characterset when pressedalong with a given key. The following example will show you
how to program a matrix.

NOTE: Fn, 9D, must be programmed in both the high and low bytes!
Supposeyou want to program the keypad shown in Figure 4-5. First you must determine
the keypad's layout. br this case,the layout is 4 rows by 3 columns. To program the scan
codes,we must first define the matrix in the RTDMOD.EXEconfiguration program. On the
screenshown in Figure 4-3, we would enablescanningand enter 4 rows and 3 columns.
After setting up the matrix size,then go to the keypad scanvalues screento enter the
scancodes.It will take 12 words to define the 12 keys in our 4 x 3 matrix. The L2 words into
which you will enter the scancodesare already highlighted on the scanvalues screen.Note
that when you do not use the entire table, the last code entered is always in the last position
on the table. This allows the unused areain the EEPROMto be available for other functions.
As shown in Figure 4-5,we would like to set up our keypad with the numerical values 0
through 9 in the positions shown, and we want to define the Fn key so that when it is
pressed,we can use the cursor position arrows, as shown in the right layout. Eachword is
divided into an upper byte and a lower byte. The lower byte defines the key when no Fn key
is pressedwith it, and the upper byte defines the key when the Fn key is pressedsimultaneously. Table 4-3 shows how to define our keypad. Note that FF is entered when a switch is
absentor a key combination is not used. Also note that we have defined the Fn key by
entering 9Dh in both the high and low bytes at row 4, column 1. \Atrhenyou enter the scan
codeson the RTDMOD.EXE'sscancode values screen,the first word in the highlighted
sectionis row 1, column 1, the secondword is row 1, column 2, etc.
Now, look at Figures 4-6 and 4-7 to seehow this example is set up on the RTDMOD.EXE
configuration screens.

NOTECMF868O.1
APPLICATION
Using The CMF8580WatchdogTimer
Embedded applications often are required to run for a long time and are subjectto all kinds
of interference,noise, and power supply glitches. The CMF8680has an onboard watchdog
timer that will reset the processorif an application is not operating properly.
The basic principle of the watchdog timer is oncethe application starts the watchdog timer it
must toggle the timer at least onceevery 1.5secondsor the watchdog timer will perform a
hardware reset. The CMF8680implementation also allows the user to disable the timer.
Example programs in Turbo C, QuickBASIC, and Turbo Pascaldemonstratethis application.
The two functions that are used are Toggle-Watchdog-Timer and Disable_Watchdog_Timer.
The watchdog timer is connectedto an I/O pin on the F8680CPU. \Atrhenthe pin is tri-stated
the timer is disabled. This is the default position after a hardware reset. The pin can be
driven high or low by using a Super StateR interrupt function. The processis to load the AH
with 14H. AL with the value to set.BH with 8CH and BL with 1H.

NOTECMF8680.2
APPLICATION
RTDNVEP.EXE:User Accessto Serial EEPROM
RTDNVEP.EXE
@Copyright Real Time Devices,lnc.1994
This Terminate-Stay-Residentprogram enablesusersto access1281,6-bitlocations in the
configuration EEPROM. Theselocations are numbered 0 to 727.
To install, type:
RTDNVEP[/]xxl
The driver will install itself on interrupt 60H by default. If the /I switch is used the supplied
interrupt will be used. For example:
To install on interrupt 66 decimal (42H), type:
RTDNVEP/I=66
or
RTDNVEP/I=0x42
To use:
The EEPROMis divided into three areas.The first 2K bits are not accessibleto the user and
are for system configuration. The last 128x 16 locations are divided between a user data area
and a keypad area.The size of eachis determined by the keypad rows and columns settings
made in RTDMOD.EXEsetup program. Eachkey defined usesone 16-bit location. The low
byte is the scancode for the key without the FN key depressed,and the high byte is the scan
code for the key if the FN key is depressed.
The generalprocedure for accessingthe User/Keypad area is to load the processorregisters
and generatean interrupt.
There are four functions supported.They are: read a location, write user location, write any
location, and read keypad rows and columns.
Function 0
To read a location:
AH = 00H
AL = addressto read O to!27
GenerateInterrupt 60H (or as set with /I)
After the interrupt returns, the results are:
AH = 0 if Readwas OK, 1 if an error occurred
AL = addressread Oto 127
BX = 16-bit value read
D-6
Function 1
To write to a user location:
AH = 01H
AL = addressto write 0 to 127-(Keypad Rows * Keypad Columns)
BX = 16-bit value to write
GenerateInterrupt 60H (or as set with /I)
After the interrupt retums, the results are:
AH = 0 if Write was OK, 1 if an error occurred
AL = addresswritten 0 to 127
Note: This function will generatean error if an accessto the keypad area is tried.
Function 2
To write to any location:
AH = 02H
AL = addressto write 0 to 727
BX = 16-bit value to write
GenerateInterrupt 60H (or as set with /I)
After the interrupt retums, the results are:
AH = 0 if Write was OK, 1 if an error occurred
AL = addresswritten 0 to 127
Function 3
To read keypad rows and columns:
AH = 03H
GenerateInterrupt 60H (or as set with /I)
After the interrupt returns, the results are:
AH = 0 if Read was OK, L if an error occurred
BL = Keypad Rows
BH = Keypad Columns
