Chapter 20 Pulse Width Modulator with Fault Protection (PMF15B6C) Module
20.3.2.32 PMF Counter C Register (PMFCNTC)
Read anytime and writes have no effect.
This register displays the state of the 15-bit PWM C counter.
20.3.2.33 PMF Counter Modulo C Register (PMFMODC)
Read anytime and write only if MTG is set.
The 15-bit unsigned value written to this register is the PWM period in PWM clock periods. Do not write
a modulus value of zero.
20.3.2.34 PMF Deadtime C Register (PMFDTMC)
Read anytime and write only if MTG is set. This register cannot be modified after the WP bit is set.

The PWM counter modulo register is buffered. The value written does not
take effect until the LDOKC bit is set and the next PWM load cycle begins.
Reading PMFMODC reads the value in the buffer. It is not necessarily the
value the PWM generator A is currently using.
