High-Impedance Output Clear Bit
0
No effect
1
Clear high-impedance output
(The PWM4xA/PWM4xB pins are back to output and this bit is
automatically cleared to logic ‘0’. where x = A, B and C)
Configure PWM4AB/PWM4BB/PWMCB Channel Polarity When these
pins are disabled
0
These pins are output according to the polarity setting when
disable (POLAB/POLBB/POLCB bits)
1
These pins are same level as the PWM4xA pins regardless of
the polarity setting when disable (POLAB/POLBB/POLCB bits,
where x = A, B and C)
Configure PWM4AA Channel Polarity
0
Start at high level (This pin is low level when disable)
1
Start at low level (This pin is high level when disable)
Configure PWM4AB Channel Polarity
0
Non-inversion signal of PWM4AA pin
1
Inversion signal of PWM4AA pin
Configure PWM4AA Channel Polarity
0
Start at high level (This pin is low level when disable)
1
Start at low level (This pin is high level when disable)
Configure PWM4AB Channel Polarity
0
Non-inversion signal of PWM4BA pin
1
Inversion signal of PWM4BA pin
Configure PWM4CA Channel Polarity
0
Start at high level (This pin is low level when disable)
1
Start at low level (This pin is high level when disable)
Configure PWM4CB Channel Polarity
0
Non-inversion signal of PWM4CA pin
1
Inversion signal of PWM4CA pin
