Hi All,
Not sure anyone has ever required to set break points within interrupts,
but this seems to be a serious limitation of the MPLAB v6.13 + Hi Tech PICC
combination.

I'm using MPLAB v6.13 along with Hi-Tech PICC compiler v8.01 PL3.
I'm unable to set breakpoints within the interrupt function in the C code,
whereas I can set the breakpoints in any other function including main.
When I was using MPLAB v5.62, with the same compiler, I did not have such
problems and I could set breakpoints even within the interrupt functions.
I'm desperately in need to set breakpoints within the interrupts to debug a
program and I want to do it using MPLAB v6.13. Any suggestions or help in
this regard would be greatly appreciated. The same problem persists with
MPLAB v6.10

Best Regards,
Naveen.P.N.

I have the same exact problem. I've gotten around it in two
different ways:

1) Pull your interrupt handler code out of the interrupt handler
proper and put it in a subroutine that the interrupt handler
calls. You should be able to set a breakpoint in this
subroutine.
2) Put a breakpoint at address 04x (i.e., the address of the
interrupt handler vector) in the "program memory" window.
For some reason, I can't set the breakpoint in this window
by double-clicking. I have to right click and select 'set
breakpoint'.

Good luck.
