Interrupt-only compare mode; several compare interrupts per timer period are
possible
Pin toggles on each compare match; several compare events per timer period are
possible
Interrupt-only compare mode; only one compare interrupt per timer period is
generated
Pin set ‘1’ on match; pin reset ‘0’ on compare time overflow; only one compare
event per timer period is generated
Two registers operate on one pin; pin toggles on each compare match; several
compare events per timer period are possible.
