1 Introduction
The ST626x starter kit provides you with all you need to start designing, developing and
evaluating programs for ST6253x, ST6255x, ST6260x, ST6263x and ST6265x
microcontrollers immediately.
The ST626x starter kit includes:
●
The ST6 assembler and linker, AST6 and LST6.
●
The ST6 Windows debugger, WGDB6.
●
The Windows ST6 microcontroller programmer, Epromer.
●
●
The ST6 starter kit board, which serves as a demonstration board and low-cost
debugging tool.
Some demonstration programs that show how ST6 microcontrollers use the starter kit
board resources.
●
Some example programs.
●
One ST62E60BF1, two ST62E62BF1 and two ST62E65BF1 sales types.
●
A complete set of paper documentation and online help.
The demonstration programs, that come pre-loaded on an ST62E65, show how the
powerful features of ST6 microcontrollers operate in a real environment. The demonstration
programs use the hardware resources provided on the starter kit board, which include reset
and data control buttons, LED indicators, a resistance trimmer, temperature control circuit
and an RS-232 interface.
Using the ST6 assembler and linker, AST6 and LST6, you can assemble and link ST6
programs. The "ST6 Family Software development tools AST6, LST6, WGDB6" User
Manual will guide you through the steps of developing, assembling and linking programs for
the ST6. The starter kit software includes a set of example programs of typical ST6
applications. These are installed in the directory C:\st6tools\sk626Xi1\examples.
For a fast-track solution for developing bug-free programs for the ST6, without the hassle of
writing assembler code, try out the ST6-Realizer program.
Once you have developed your ST6 program, you can use the Windows-based ST6
program debugger, WGDB6/SIMULATOR, together with the starter kit board, as a low-cost
but powerful debugging tool. WGDB6 includes an ST6 simulator, that simulates the
execution of your program, and uses the ST6 that is plugged into the starter kit board to
emulate all transactions that are performed with the data space. Thus, using the starter kit
board with WGDB6, you can view how the microcontroller peripherals behave when your
program is executed. WGDB6 includes powerful debugging features, such as source-level
debugging, instruction and conditional memory access breakpoints and selective trace
recording. The "ST6 Family Software development tools AST6, LST6, WGDB6" User
Manual and online help will lead you through the debugging process using WGDB6.
When your program is ready, Epromer provides you with an easy-to-use Windows interface,
which lets you prepare executable code, then write it to the ST6 microcontroller that is
plugged into either one of the DIL sockets on the starter kit board, or your own in-circuit
application board that is connected to the starter kit board.
To observe and evaluate the consequences of your program on the resources it controls,
you can run it on an ST6 microcontroller that is plugged into the starter kit board. If it

controls a resource that is not included on the starter kit board, you can connect your own
resource to the board.
Instructions for use - Warning

Demonstration selector jumpers
The demonstration selector is made up of 6 jumpers W26 to W31 (marked 13 on the Starter
kit board diagram on page 13), with each jumper connected to a resistor. Each resistor
generates a different voltage.
After reset, the voltage value generated by the resistor whose jumper is installed is sent to
PA3 on the ST6265x. PA3 is programmed as an A/D converter. The program installed on the
ST6265x uses the input from PA3 to select the appropriate demo. The following table lists
the voltage values generated by each resistor:

Demo 1 - Sound generation
After RESET, this program generates a PWM signal at the output of the AUTO RELOAD
TIMER peripheral (PB7), which is connected to the Audio Transducer.
The frequency of the PWM signal can be adjusted by pressing the + (increase) or the (decrease) pushbuttons.
An oscilloscope probe can be positioned on the W15-PB7 jumper to observe the PWM
signal.
4.1.2
Demo 2 - Music box
After RESET, this program produces 5 tunes that are played by the Audio Transducer. The
sound frequencies are generated at the AUTO RELOAD TIMER output peripheral (PB7),
used in PWM mode.
The LED that is turned on indicates the tune to be played (1 through 5). To select the tune to
play, press the + button.
The music starts playing when the - button is pressed.
The tempo of the music can be modified using the voltage trimmer (marked 6 on the Starter
kit board diagram on page 13). This is connected to PA4 I/O programmed as Analog input.
Once the music has finished playing, another tune can be selected and played the same
way.

A PWM signal is generated by the ARTimer at PB7 output. The voltage value at the output
of the RC integrator circuit is controlled by the PWM duty cycle.
After RESET, the program:
●
●
Generates a 64 KHz frequency PWM signal at the Auto Reload Timer output. The duty
cycle is initialized at 50%.
Decreases/increases the duty cycle value each time the - or + button is pressed (2%

Using the starter kit board as a hardware simulator
WGDB6, the ST6 debugger that runs under Windows, lets you test your programs without
having to program the EPROM of your target ST6. Depending how much information you
want, and how close to real life you want your test environment to be, you can use WGDB6
in one of three ways:
●
●
●
As a software simulator. If you use WGDB6 as a simulator, you need not attach any
additional hardware to your PC. The ST6 simulator program, that comes with WGDB6
and is run when you run WGDB6/Simulator, simulates the execution of your program,
letting you step through the code and see what happens as the program runs. WGDB6
simulator includes Wave Form Editor, which simulates the output of the pins on your
target ST6 in relation to inputs that you define, enabling you to see how its peripherals
react to the inputs they receive.
With an ST6 hardware emulator. Emulators are hardware systems that act as your
target microcontroller, at the same time capturing detailed information, such as which
areas of memory are accessed by the program and what happens when they are
accessed. In this case, WGDB6/Emulator provides an interface between the emulator
and your PC, displaying data captured by the emulator and letting you implement the
WGDB6 features in the emulator, such as software or hardware breakpoints.
With the starter kit board as a hardware simulator. This is a cross between the above
two. The WGDB6 software simulator simulates the execution of your program, but
each time the data space is accessed, it accesses that of the ST6 that is plugged into
your starter kit board. Thus, using the starter kit board with WGDB6, you can view how
the real microcontroller peripherals behave when your program is executed.
This section describes the third option, how to use the starter kit board as a hardware
simulator.
You can use the starter kit board to emulate any ST6252x, ST6253x, ST6255x, ST6260x,
ST6262x, ST6263x or ST6265x microcontroller. Note, however that you must use the preprogrammed ST6265x microcontroller, labelled DEMOK65 supplied with the kit for hardware
simulation. Thus, when simulating programs designed for other microcontrollers, make sure
that you do not use resources that are not available on the microcontroller your application
is designed for.

Using the starter kit board as a hardware simulator
The data transmission driver
Data is transferred between the simulated peripheral registers and the ST626x registers via
the host PC’s parallel port. The DEMOK65.HEX program, with which the ST6265x
microcontroller that is plugged into the starter kit board must be loaded includes the
transmission driver.
The data transfer driver uses the following bits:

Technical limitations
The starter kit board has the following limitations when used with WGDB6 as a hardware
simulator:
●
●
●
●
●
Real-time program execution is not supported.
Resetting the ST6265x by power on, pressing the Reset button or external reset does
not reset the simulated ST6 core. To perform a complete simulated reset, use the
WGDB6 reset command instead.
Interrupts sent by the ST6265x microcontroller are not supported by the WGDB6
simulator.
The pins: NMI, PA0, PA1 and PA2 on the ST6265x microcontroller are used for
communications with the host PC, and are thus not available for simulation.
You cannot modify the D0, D1 and D2 bits of the DDRA, ORA and DRA registers.

Programming ST6 microcontrollers
You can use the starter kit board, in conjunction with the program Epromer, to program
ST6252x, ST6253x, ST6255x, ST6260x, ST6262x, ST6263x or ST6265x microcontrollers.
You can also perform in-circuit programming of ST6252x, ST6253x, ST6255x, ST6260x,
ST6262x, ST6263x or ST6265x OTP/EPROM microcontrollers using your own board,
connected to the starter kit board via the connector J1 (marked 1 on the Starter kit board
diagram on page 13).

The PB2, PB3, OSCIN and RESET signals on the J2 connector are used during ST6
programming, thus if you have connected an external resource to J2, you must disconnect
these signals before using the starter kit board for programming.
The PB2, PB3, OSCIN and RESET pins are used by the system during programming. The
programming signals are therefore switched to different pins of the DIL-28 socket.

In-circuit programming
You can perform in-circuit programming of ST6252x, ST6253x, ST6255x, ST6260x,
ST6262x, ST6263x or ST6265x OTP/EPROM microcontrollers using your own board,
connected to the starter kit board via the connector J1 (marked 1 on the Starter kit board
diagram on page 13).
7.3.1
Application board connections
The following paragraphs specify the connection requirements between your application
board and the starter kit board.
The application board must have a suitable 16-way connector (8x2 header HE10) to be
connected via a 16-way cable to connector J1 (marked 1 on the Starter kit board diagram on
page 13) on the starter kit board.
The following table shows the required pin connections:

VDD
Use of the VDD connection is optional, depending on whether the application board supply
can or cannot be disconnected. If the application board supply is disconnected, you can
supply it through pins 14 an 16 of the connector, as long as the total load current does not
exceed 100 mA, and the capacitive load is less than 50 mF.
If the application board has its own power supply, its voltage must be set to 5V, so that logic
levels are compatible with those of the starter kit board.
OSCin
Synchronises the programming operations using a clock generated by the programming
tool. OSCin is located on the application board, and must be directly connected to Pin 5 on
the 16- way connector. No isolation is needed as long as a quartz crystal or ceramic
resonator is used in the application. If an external clock generator is used in the application,
it must be disconnected during in-circuit programming.
RESET
Controls the programming mode entry. To prevent signal level contention, RESET must be
directly connected to Pin 9 on the 16-way connector, and must be isolated from other nodes
on the application board. Any direct connection to VDD, VSS or an output must be avoided.
36/45
Doc ID 5112 Rev 2
UM0002
Programming ST6 microcontrollers
This pin can be connected to a CMOS input, a 2 KΩ pull-up, a 10 KOhm pull-down or left
open (Internal pull-up). The capacitive load of the RESET pin should not exceed 1 mF.
Pins 1 and 7 on the 16-way connector are used to establish communications between the
programming tool and the microcontroller.
To prevent signal-level contention, Pins 1 and 7 must be directly connected to PB3 and PB2
on the 16-way connector, and must be isolated from other nodes on the application board.
Any direct connection to VDD, GND or an output must be avoided. These pins may be
connected to a CMOS input, a 2 KΩ pull-up, a 10 KOhm pull-down or left open (Internal pullup).
If pin 3 on the 16-pin connector is connected to the target device, the same applies.
Connection to pin 3 is not necessary if a high voltage level is guaranteed by the board
design.
Some I/O pins are not connected to the 16-way connector and must be set to a high level
during programming. This is normally achieved by the RESET signal sent by the
programming tool through the 16-way cable, setting the I/O pins as inputs with an internal
300 KΩ pull-up. To keep these I/O lines high, direct connection of these pins to GND or to
any other signal at low level (even temporarily) must be avoided. Only connections to
another CMOS input, to an external pull-up or a 10 MΩ pull-down is allowed.
The signals on PB3 and PB5 (if not directly biased through pin 3 of the 16-way connector)
must be kept at a high voltage level.
The Vpp/TM pin must not be directly connected to GND/VSS on the application board, to
avoid any conflict with the programming voltage provided by the programming tool via pin 13
on the connector. This pin should be pulled down by a resistor with minimum value of 10
KΩ. You must add a 100 nF ceramic capacitor between Vpp/Test and VSS.
