How to reset PIC in Software?

Hai

Which is the best method to reset a PIC from its own software?


Will a goto 00 clear the call stack?

just enable it when u want to reset the PIC after a while (depend on the value in the WDT).

My programe works in WDT disabled mode.


I doubt weather WDT can be enabled "on the fly"

Thanks

If you plan to use GOTO 00 as software reset you will need to add in the beginning of the code set of SETs/RESETs to specified registers, otherwise jump to 00 will be executed like any other jump ..
( see data sheet of a particular PIC for the reset values of crucial registers) ..

Another option, however not used very often, is to connect one of I/O pins to the MLCR and execute reset that way ..

PIC18 devices have RESET instruction.
On PIC16 there is no softreset, but it is possible to configure a peripheria (like WDT) to reset the chip.
