Once the internal WDT oscillator (RC oscillator with a period of 31 s/5V normally) is selected first divided by 256 (8-stage) to get the nominal time-out period of 8ms/5V. This time-out period may vary with tempera- tures, VDD ...
Page 13
The WDT time-out during HALT is different from other chip reset conditions, since it can perform a warm re - set that resets only the Program Counter and SP, leav- ing the other circuits in their original state. Some regis- ...
