Well - I am still having watch dog problems on the 2106 !!

I implimented the code as below. If I didn't call watchdogfeed I would
get a regular reset every 20 seconds (though I calculated it at about
1/4 seconds with 14Mhz Xtal)

I modified the code to call watchdogfeed ever 20 micro seconds or so (in
my main loop) and the processor started resetting erratically every 10
seconds or so!

Calling watchdogfeed every second has stopped this and the processor
APPEARS to be operating properly. BUT !!! if calling watchdogfeed has a
1 in 1000000 chance of resetting the processor, have I just reduced my
random resets to once per 10 days or so !

Does anyone have any knowlege of this?

void watchdogfeed(void){
WDFEED=0xAA;
WDFEED=0x55;
}

int main(void) {

...

WDTC = 0x1000000;
WDMOD= 0x03;
WDFEED=0xAA;
WDFEED=0x55;

...

}
