PPOL3 — PWM Channel 3 Polarity
PPOL2 — PWM Channel 2 Polarity
PPOL1 — PWM Channel 1 Polarity
PPOL0 — PWM Channel 0 Polarity
Depending on the polarity bit, the duty registers may contain the count
of either the high time or the low time. If the polarity bit is zero and left
alignment is selected, the duty registers contain a count of the low
time. If the polarity bit is one, the duty registers contain a count of the
high time.
