PWM_TC
PWMxTermCnt is used to adjust the output frequency of
the PWM. PWMxTermCnt gives the PWM up to 16-bit
resolution.
PWMxTermCnt is double buffered to allow it to be
programed statically (PWM is stopped) or dynamically
(PWM is running).
Programmed dynamically, PWMxTermCnt is updated at
the end of a PWM cycle to prevent any output glitches or
errors. Reading the register reflects what was written to it,
not the state of the counter.
