POUT7:POUT0: PWM Manual Output bits⁽¹⁾
1 = Output on PWM I/O pin is ACTIVE when the corresponding PWM output override bit is
cleared.
0 = Output on PWM I/O pin is INACTIVE when the corresponding PWM output override bit is
cleared.
Note 1: 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
