Polarity control bits HPOL and LPOL define PWM signal output active and inactive states, PWM states
generated by the fault inputs or PWM manual override.
PWM6 and PWM7 output channels are only available on the PIC18F4X21 devices.
When PWMPIN = 0, PWMEN<2:0> = 101 if device has eight PWM output pins (40 and 44-pin devices)
and PWMEN<2:0> = 100 if the device has six PWM output pins (28-pin device). PWM output polarity is
defined by HPOL and LPOL.
This bit is reserved on PIC18F2X31 devices and should be maintained set (i.e., equal to ‘1’).
For PIC18FX431 devices only.
