The Output Compare module (OCMP) is used to gen-
erate a single pulse or a train of pulses in response to
selected time base events. For all modes of operation,
the OCMP module compares the values stored in the
OCxR and/or the OCxRS registers to the value in the
selected timer. When a match occurs, the OCMP mod-
ule generates an event based on the selected mode of
operation.
