Description
Output Select 15 to 8
These bits select the PWM output phase. Bits OS15 to
OS8 correspond to outputs PW15 to PW8.
0: PWM direct output (PWDR value corresponds to high
width of output)
1: PWM inverted output (PWDR value corresponds to
low width of output)
9.3.4 PWM Output Enable Registers A and B (PWOERA, PWOERB)
Each PWOER switches between PWM output and port output.
