PWM_DC is used in conjunction with PWMxTermCnt to
adjust the output duty cycle of PWM. PWMxDutyCycle is
double buffered to allow it to be programed statically
(PWM is stopped) or dynamically (PWM is running).
Programmed dynamically, PWMxDutyCycle 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.
Reserved. Unknown During Read.
Enable PWM
0 - Disable/Stop PWM. The PWM is actually stopped when
it reaches the end of its current cycle. PWM output is:
0 - If PWM_INV = 0
1 - if PWM_INV = 1
1 - PWM is Enabled. When in normal mode writing a one
will start the PWM.
PWMxTermCnt is updated with its new buffered value.
PWMxDutyCycle is updated with its new buffered value.
