I've never run into this combination before so I thought I would forward
this to the list for Soni...

...I would assume the thing to do is disable the WDT before you SLEEP and
then re-enable it on wake up, but I've never had cause to use SLEEP so I
don't really know.

Dear sir ,

     I am final year student and doing my final project on development
board.


    I am using pic12c509A in this project.But I am facing problem while
using
watch dog timer.

problem is that when i use sleep instruction the device become reset .

i want to know that how it can work normally after sleep instruction .

I have also use clrwdt but situation is same.

Before it I have effeciently used WDT in PIC16f84.

Please help me in this regard

your,s

Soni


the code is
==================================================


        LIST    p=12C509A
        #include "P12C509A.INC" ; Include header file
        __CONFIG        _mclre_off & _cp_off & _wdt_on & _xt_osc


START
        clrwdt
        CLRF    GPIO
        MOVLW   B'0001000'
        TRIS    GPIO
        MOVLW   B'11001111'
        OPTION


sense
        clrwdt
        btfsc   gpio,3
        goto    sense
        bsf     gpio,0
        sleep
        bcf     gpio,0
        bsf     gpio,1
        sleep
        bcf     gpio,1
        bsf     gpio,2
        sleep
        bcf     gpio,2
        sleep

        GOTO    SENSE
        END
