msec counter for avr.
/*
Calculated for 20MHz:
(((1sec/20000000) * 8 )* 250 )* 10 =0.001sec
freq presc ticks multiplayer 1msec
so at freq 20mhz, we need to prescale with 8, count to 249, and then multiple by 10 to get 1msec out of the counter.
This needs some calculations for each different frequency.
Adjust prescalar and ticks until you get the "multiplayer" to be an integer!
