Getting Started Guide
Special Function Registers
Registers that control I/O processor functions, I/O status, timers, or other
modes or peripherals.
Stack
“Push-Down” list of calling routines. Each time a PICmicro microcontroller
executes a call, the software pushes the return address to the stack. A RET or
RETLW command pops the address from the stack.
Static RAM, or SRAM
Static Random Access Memory. Program memory you can Read/Write on the
target board that does not need refreshing frequently.
Step-Into
This command is the same as Single Step. Step-Into (as opposed to StepOver) follows a CALL instruction into a subroutine.
Step-Over
Step-Over allows you to debug code without stepping into subroutines. When
stepping over a CALL instruction, the next breakpoint will be set at the
instruction after the CALL. If for some reason, the subroutine gets into an
endless loop or does not return properly, the next breakpoint will never be
reached.
The Step-Over command is similar to Single Step except for its handling of
CALL instructions.
Stopwatch
A 48-bit counter for measuring execution cycles.
Symbol
An label usually produced by an assembler or compiler that refers to machine
locations by function names, variable locations, constant declarations, source
line-number, or other reference to user source code.
System Button
The System Button is located in the upper left corner of Windows and some
dialogs. This button usually has “Minimize”, “Maximize”, and “Close.” In some
MPLAB windows, additional modes or functions can be found under the
System Button.
Target
Refers to a user application.
Target Application
Firmware residing on the target board.
Target Board
The circuitry and programmable device that makes up the target application.
