5.2.3. 16-bit Output Compare Timing
This section explains the 16-bit output compare timing.
When the free-run timer value matches the compare register value, the output compare generates a compare
match signal and inverts the output to generate an interrupt. When a compare match occurs, the output is
inverted in synchronization with the counter count timing.
