REGISTER 14-6: PWMxCON: ENHANCED PWM CONTROL REGISTER
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
PxRSEN PxDC<6:0>
bit 7 bit 0
Legend:
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 CCPxASE bit clears automatically once the shutdown event goes
away; the PWM restarts automatically
0 = Upon auto-shutdown, CCPxASE 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 * TOSC) cycles between the scheduled time when a PWM signal
should transition active and the actual time it transitions active
REGISTER 14-7: PSTRxCON: PWM STEERING CONTROL REGISTER
(1)
U-0 U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-1
— — — STRxSYNC STRxD STRxC STRxB STRxA
bit 7 bit 0
Legend:
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 7-5 Unimplemented: Read as ‘0’
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.
