Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
bit 7
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
bit 6-0
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.
