Timer/Counter1 is a general purpose high speed Timer/Counter module, with three independent
Output Compare Units, and with PWM support.
The Timer/Counter1 features a high resolution and a high accuracy usage with the lower pres-
caling opportunities. It can also support three accurate and high speed Pulse Width Modulators
using clock speeds up to 64 MHz. In PWM mode Timer/Counter1 and the output compare regis-
ters serve as triple stand-alone PWMs with non-overlapping non-inverted and inverted outputs.
Similarly, the high prescaling opportunities make this unit useful for lower speed functions or
exact timing functions with infrequent actions. A simplified block diagram of the Timer/Counter1
is shown in
