W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
bit 6-0
PRSEN: PWM Restart Enable bit
1 = Upon auto-shutdown, the ECCPASE bit clears automatically once the shutdown event goes away;
the PWM restarts automatically
0 = Upon auto-shutdown, ECCPASE must be cleared in software to restart the PWM
PDC<6:0>: PWM Delay Count bits⁽¹⁾
Delay time, in number of FOSC/4 (4 * TOSC) cycles, between the scheduled and actual time for a PWM
signal to transition to active.
Note 1: Reserved on PIC18F2X80 devices; maintain these bits clear.

ECCPASE: ECCP Auto-Shutdown Event Status bit
1 = A shutdown event has occurred; ECCP outputs are in shutdown state
0 = ECCP outputs are operating
ECCPAS<2:0>: ECCP Auto-Shutdown Source Select bits
111 = RB0 or Comparator 1 or Comparator 2
110 = RB0 or Comparator 2
101 = RB0 or Comparator 1
100 = RB0
011 = Either Comparator 1 or 2
010 = Comparator 2 output
001 = Comparator 1 output
000 = Auto-shutdown is disabled
PSSAC<1:0>: Pins, A and C, Shutdown State Control bits
1x = Pins, A and C, tri-state (PIC18F4X80 devices)
01 = Drive Pins, A and C, to ‘1’
00 = Drive Pins, A and C, to ‘0’
PSSBD<1:0>: Pins, B and D, Shutdown State Control bits⁽¹⁾
1x = Pins, B and D, tri-state
01 = Drive Pins, B and D, to ‘1’
00 = Drive Pins, B and D, to ‘0’
