COMPARE Compare Value
When the LPTMR is enabled and the CNR equals the value in the CMR and increments, TCF is set and
the hardware trigger asserts until the next time the CNR increments. If the CMR is 0, the hardware trigger
will remain asserted until the LPTMR is disabled. If the LPTMR is enabled, the CMR must be altered only
when TCF is set.
