Legend:
R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-6
CMPL<1:0>:
Complementary Mode Output Assignment Steering Sync bits
00
= See STR<D:A>
01
= PA and PB are selected as the complementary output pair
10
= PA and PC are selected as the complementary output pair
11
= PA and PD are selected as the complementary output pair
bit 5
Unimplemented:
Read as ‘0’
bit 4
STRSYNC:
Steering Sync bit
1
= Output steering update occurs on the next PWM period
0
= Output steering update occurs at the beginning of the instruction cycle boundary
bit 3
STRD:
Steering Enable bit D
1
= PxD pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxD pin is assigned to the port pin
bit 2
STRC:
Steering Enable bit C
1
= PxC pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxC pin is assigned to the port pin
bit 1
STRB:
Steering Enable bit B
1
= PxB pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxB pin is assigned to the port pin
bit 0
STRA:
Steering Enable bit A
1
= PxA pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxA pin is assigned to the port pin
Note 1:
The PWM Steering mode is available only when the CCPxCON register bits, CCPxM<3:2> = 11 and
PxM<1:0> = 00.
PxM<1:0> = 00.
