I first learnt about microprocessors on the Motorola 6800 family back in the mid 70's They are great, the timers/counters have hardware interrupts, when they are activated (like a timers/counters flag been set) , it sends the Micro off to FFFx and FFFx+1 (I can not remember the correct address) to get the 16 bit address, of were the start of the program is to service whatever activated the interrupt, Just like when you start the Micro from a reset, the address of the start of the program would be in address FFFE & FFFF. However the Atmel products don't seem to have this feature, the software have to continually look to see if the timers/counters flag have been set, with a software loop. Is this always true on the Atmel products, or is it I have not got to know all the Atmel family yet? From Eric
