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 PIC18F4331/4431 devices.
When PWMPIN = 0, PWMEN<2:0> = 101 if the 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 devices). PWM output
polarity is defined by HPOL and LPOL.
Unimplemented: Read as ‘0’
T1OSCMX: Timer1 Oscillator Mode bit
1 = Low-power Timer1 operation when microcontroller is in Sleep mode
0 = Standard (legacy) Timer1 oscillator operation
HPOL: High Side Transistors Polarity bit (i.e., Odd PWM Output Polarity Control bit)
1 = PWM1, 3, 5 and 7 are active-high (default)
0 = PWM1, 3, 5 and 7 are active-low
LPOL: Low Side Transistors Polarity bit (i.e., Even PWM Output Polarity Control bit)
1 = PWM0, 2, 4 and 6 are active-high (default)
0 = PWM0, 2, 4 and 6 are active-low
PWMPIN: PWM Output Pins Reset State Control bit
1 = PWM outputs are disabled upon Reset (default)
0 = PWM outputs drive active states upon Reset
Unimplemented: Read as ‘0’
