The pre-scaler in the uC can't divide by a multiple of 10 (just 1/32, 1/64, 1/128, etc) so although you start with a nice 10Mhz clock, you end up with an ISR that runs every 10/32 or so on cycles. You might want to look at the page on timers.' at: '' Christian Hultqvist Says: " how do i get this to work with 10mhz external reference clock/xtal "
