I'm having a problem with the reset of my d60a circuit from time to time. Once in a while, the reset won't work and my program goes into never-never land. It sometimes returns after 4 seconds, making me believe the watchdog timer times out eventually, and resets the chip. Since I set the timer to time out at .25 seconds in code, I know it is never getting to this point in the program. Seems to me I have a "runaway code" problem due to the reset circuit, that cannot be changed on our circuit (encapsulated).
Is there any code that could be placed in unused memory locations that would "force" a reset?
