PRSEN: PWM Restart Enable bit
1
=
Upon auto-shutdown, the PWMASE shutdown bit clears automatically once the shutdown
condition goes away. The PWM restarts automatically
0
=
Upon auto-shutdown, the PWMASE must be cleared in firmware to restart the PWM.
bit 6
PASEN: PWM Auto-Shutdown Enable bit
0
=
PWM Auto-Shutdown is disabled
1
=VIL on INT pin will cause Auto-Shutdown event
bit 5
BLANK2: PH2 Blanking bit
1
=
The PH2 pin is active for a minimum of 1/2 of an FOSC clock period after it is set
0
=
The PH2 pin is reset as soon as the comparator trigger is active
bit 4
BLANK1: PH1 Blanking bit
1
=
The PH1 pin is active for a minimum of 1/2 of an FOSC clock period after it is set
0
=
The PH1 pin is reset as soon as the comparator trigger is active
bit 3-2
SYNC<1:0>: SYNC Pin Function bits
0X
= SYNC pin not used for PWM. PWM acts as its own master. RB6/SYNC pin is available
for general purpose I/O.
10
= SYNC pin acts as system slave, receiving the PWM counter reset pulse
11
= SYNC pin acts as system master, driving the PWM counter reset pulse
bit 1
PH2EN: PH2 pin enabled
1
=
The PH2 pin is driven by the PWM signal
0
=
The PH2 pin is not used for PWM functions
bit 0
PH1EN: PH1 pin enabled
1
=
The PH1 pin is driven by the PWM signal
0
=
The PH1 pin is not used for PWM functions
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = bit is set
‘0’ = bit is cleared
x = bit is unknown
