PMF Counter C — This register displays the state of the 15-bit PWM C counter.
PMF Couner Modulo C — 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.
Note: 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.
