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.
Unimplemented: Read as ‘0’
PWMEN2:PWMEN0: PWM Module Enable bits
111 = All odd PWM I/O pins enabled for PWM output
110 = PWM1, PWM3 pins enabled for PWM output
101 = All PWM I/O pins enabled for PWM output
100 = PWM0, PWM1, PWM2, PWM3, PWM4 and PWM5 pins enabled for PWM output
011 = PWM0, PWM1, PWM2 and PWM3 I/O pins enabled for PWM output
010 = PWM0 and PWM1 pins enabled for PWM output
001 = PWM1 pin is enabled for PWM output
000 = PWM module disabled; all PWM I/O pins are general purpose I/O
