unavailable bits return a zero

Pulse Width Channel 7–0 Polarity Bits

0 PWM channel 7–0 outputs are low at the beginning of the period, then go high when the duty count is

1 PWM channel 7–0 outputs are high at the beginning of the period, then go low when the duty count is

PWM Clock Select Register (PWMCLK)

PPOLx register bits can be written anytime. If the polarity is changed while

a PWM signal is being generated, a truncated or stretched pulse can occur

during the transition
