Breakpoints

4.4.3
A breakpoint is a state where the processor halts after a certain condition is
met. The breakpoints are software breakpoints and can be set at any program
memory address location.
The ICEPIC In-Circuit Emulator provides the following ways to set a
breakpoint:
Break on Address Match
Break on Address Match allows you to halt the processor when the processor
program counter equals a certain value. The processor breaks before the
valid instruction is executed. For example, if a breakpoint is set at address
5Ah, then the processor breaks after executing the instruction at address 5Ah.
Break on Stack Overflow
Break on Stack Overflow causes the ICEPIC In-Circuit Emulator to execute a
break when the stack overflows.
Break on Watchdog Timer
If enabled, the ICEPIC In-Circuit Emulator executes a break when a watchdog
timer time-out generates a reset.

• Break on Address Match
• Break on Stack Overflow
• Break on Watchdog Timer
• Break on User Halt
MPLAB IDE limits the number of named events to a maximum of
16 in the breakpoint dialog.
On multicycle instructions, the ICEPIC In-Circuit Emulator ignores
extra (noninstruction) fetches and breaks only on a valid instruc-
tion
The ICEPIC In-Circuit Emulator only supports Break on Stack
Overflow for the PIC16CXXX family.
The ICEPIC In-Circuit Emulator only supports Break on Watchdog
Timer for the PIC16CXXX family.
