Bit resets to ‘0’ with Two-Speed Start-up and LP, XT or HS selected as the Oscillator mode or Fail-Safe
mode is enabled.
The PWM Steering mode is available only when the CCP1CON register bits CCP1M<3:2> = 11 and
P1M<1:0> = 00.
P1RSEN: PWM Restart Enable bit
1 = Upon auto-shutdown, the CCP1ASE bit clears automatically once the shutdown event goes
0 = Upon auto-shutdown, CCP1ASE must be cleared in software to restart the PWM
P1DC<6:0>: PWM Delay Count bits
P1DC1 = Number of F
Unimplemented: Read as ‘0’
STR1SYNC: 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
Reserved: Read as ‘0’. Maintain these bits clear.
STR1B: Steering Enable bit B
1 = P1B pin has the PWM waveform with polarity control from CCP1M<1:0>
0 = P1B pin is assigned to port pin
STR1A: Steering Enable bit A
1 = P1A pin has the PWM waveform with polarity control from CCP1M<1:0>
0 = P1A pin is assigned to port pin
