bit 7
bit 0
Legend:
R = Readable bit
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
bit 7
PxRSEN:
PWM Restart Enable bit
1
= Upon auto-shutdown, the ECCPxASE bit clears automatically once the shutdown event goes
away; the PWM restarts automatically
0
= Upon auto-shutdown, ECCPxASE must be cleared in software to restart the PWM
bit 6-0
PxDC<6:0>:
PWM Delay Count bits
PxDCx = Number of F
OSC
/4 (4 * T
OSC
) cycles between the scheduled time when a PWM signal
should
transition active and the actual time it transitions active

bit 4
STRxSYNC:
Steering Sync bit
1
= Output steering update occurs on next PWM period
0
= Output steering update occurs at the beginning of the instruction cycle boundary
bit 3
STRxD:
Steering Enable bit D
1
= PxD pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxD pin is assigned to port pin
bit 2
STRxC:
Steering Enable bit C
1
= PxC pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxC pin is assigned to port pin
bit 1
STRxB:
Steering Enable bit B
1
= PxB pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxB pin is assigned to port pin
bit 0
STRxA:
Steering Enable bit A
1
= PxA pin has the PWM waveform with polarity control from CCPxM<1:0>
0
= PxA pin is assigned to 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.
