PMOD3:PMOD0: PWM Output Pair Mode bits
For PMOD0:
1 = PWM I/O pin pair (PWM0, PWM1) is in the Independent mode.
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.
Note 1: Reset condition of PWMEN bits depends on PWMPIN device configuration bit.
2: When PWMEN2:PWMEN0 = 101, PWM[5:0] outputs are enabled for
PIC18F2X31 devices; PWM[7:0] outputs are enabled for PIC18F4X31devices.
When PWMEN2:PWMEN0 = 111, PWM outputs 1, 3 and 5 are enabled in
PIC18F2X31devices; PWM outputs 1, 3, 5 and 7 are enabled in PIC18F4X31
devices.
3: Unimplemented in PIC18F2X31 devices; maintain these bits clear.
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = bit is cleared x = bit is unknown
