Many thanks for those who help me! (:
I got a problem here...
If i were to use 3 types of interrupts(external interrupt0, timer0 and timer1) in one single program, how should i go about writing the codes in the program?
read any datasheet for modern derivative that can be woken up from sleep mode by e.g. int0. I recall none that will wake up fron an edge int, all I recall require a level int to wake up.

Ah, I understand what you meant.
