Hi, I have a some project on 16C63( /JW chip )..... and I want to run it with WDT. I set: OSC XT (4MHz) CP off WDTE on PWRTE off BODEN off OPTION REG: PS0:2 111 (1:128 prescaler) PSA 1 (prescaler to WDT) (i.e. 2.3 sec WDT period) and I inserted CLRWDT-commands into my programm.... As a result: WDT works and resets chip though CLRWDT in the my programm...Why? What do I wrong?
