PBP and assembler mixing - weird goings-on?
Hi,
I've been dabbling with mixing some asssembler with PBP and can't understand why the following is happening... Consider this code:
;-------------------------------
VAR BYTE loop
main: FOR loop = 0 to n
TOGGLE PORTb.3
NEXT
ASM
_fred
clrw
movwf (anywhere)
movlw .255
movwf (anywhere)
goto _fred
ENDASM
END
;-------------------------------
Sure enough, when this code is run, the loop executes for n times, then the code falls through into the assembly language section, but instead of looping infinitely to _fred, it pops back out and goes back to main: ???
Why is it doing this?

Watch Dog Timer timeout ?
If you have the watchdog timer enabled, the processor will reset and go back to main.
