Hello all, I was wondering what the exact behaviour of the timer is. Firts I set the timer interrupt and pre-scalers. When i need the timer I write 0x00 to it and it starts to run. Gives an interrupt on 0xFF->0x00. I handle the interrupt. But what then ???????? I noticed that i have to write 0x00 to it again to start it ! Is this correct ??? grtz, Simon ____________________________________________________________ Do You Yahoo!?
