Greetings,

i'm new to this list (in fact this is my first post :)

well, i have some questions about WDT. i need some understanding about
it.

1) what will WDT do ? is it the WDT will interrupt at every preset time
to check if the program hang ?

2) if the prescaler is set to 1:128 for WDT, will this mean the WDT will
interrupt every 6.5536 ms (20Mhz crystal) ? if so, is it possible to
have longer period ?

TIA :)

regards,
