0 = PWM I/O pin pair (PWM0, PWM1) is in the Complementary mode
For PMOD1:
1 = PWM I/O pin pair (PWM2, PWM3) is in the Independent mode
0 = PWM I/O pin pair (PWM2, PWM3) is in the Complementary mode
For PMOD2:
1 = PWM I/O pin pair (PWM4, PWM5) is in the Independent mode
0 = PWM I/O pin pair (PWM4, PWM5) is in the Complementary mode
For PMOD3:⁽³⁾
1 = PWM I/O pin pair (PWM6, PWM7) is in the Independent mode
0 = PWM I/O pin pair (PWM6, PWM7) is in the Complementary mode

Reset condition of PWMEN bits depends on PWMPIN Configuration bit.
When PWMEN2:PWMEN0 = 101, PWM<5:0> outputs are enabled for PIC18F2331/2431 devices;
PWM<7:0> outputs are enabled for PIC18F4331/4431 devices.
When PWMEN2:PWMEN0 = 111, PWM outputs 1, 3 and 5 are enabled in PIC18F2331/2431 devices;
PWM outputs 1, 3, 5 and 7 are enabled in PIC18F4331/4431 devices.
Unimplemented in PIC18F2331/2431 devices; maintain these bits clear.
