Output controlled by
other pin-shared function ^{Output Inverts}
When PTnPOL = 1
PWM Output Mode (n=0~2)
Note: 1. Counter cleared by CCRP
2. A counter clear sets the PWM Period
3. The internal PWM function continues running even when PTnIO[1:0]=00 or 01
4. The PTnCCLR bit has no influence on PWM operation
