OK, one guy wrote back and said it wasn't possible, but I don't think that's correct, because the PWM can also trigger interrupts. Again: I need to drive more than 20 mA to an LED being PWMed by an ATtiny25. I want to use the PWM module on timer/counter0 to drive an interrupt routine that sets and clears, as appropriate, a pair of GPIOs driving my LED to ~~30-35 mA. ( I really don't have the physical room in my environment for one more transistor, very very tight environment) Problem is, the data sheet material on this particular issue has me confused, not clear on what I should be doing. Any help? tom
