DEBUGGING THE CODE
The MPLAB ICD 2 In-Circuit Debugger can be used to run, halt and step the code. A
breakpoint can be set to halt the program after the code has executed the instruction
at the breakpoint. The contents of the RAM and registers can be viewed whenever the
processor has been halted.
The MPLAB ICD 2 In-Circuit Debugger uses the following function keys to access the
main debugging functions:
<F5> Halt
<F6> Reset
<F7> Single Step
<F9> Run
In addition, there are more functions available by right clicking on a line of source code.
The most important of these are “Set Breakpoint” and “Run to Cursor”.
3.5.1
• From the View menu, select View>Program Memory.
• On the Program Memory window, select the Symbolic tab, as shown in
• Press <F5> to halt the processor and press <F6> to reset. The program memory
The instruction at this location is goto 0x000100. This code is added by the linker to
make the program branch to the start of the code in the Lab1.c file. From location
0x000100 executable code starts.
