timers
16-bit
output
compare
Number of channels : 8
Pin change timing : Free run timer register value equals output compare register value.
16-bit
input
capture
Number of channels : 2
Saves the value of the freerun timer register when a pin input occurs (rising edge, falling
edge, either edge) .
16-bit reload timer
Number of channels : 2
Count clock frequency : 0.125, 0.5, or 2.0 µs for a 16 MHz machine clock
Can be used to count an external event clock.
