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 1-0
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
000 =Auto-Shutdown is disabled
001 =Comparator output change
010 =Auto-Shutdown is disabled
011 =Comparator output change(1)
100 =VIL on INT pin
101 =VIL on INT pin or Comparator change
110 =VIL on INT pin(1)
111 =VIL on INT pin or Comparator change
PSSAC<1:0>: Pin P1A Shutdown State Control bits
00 = Drive pin P1A to ‘0’
01 = Drive pin P1A to ‘1’
1x = Pin P1A tri-state
PSSBD<1:0>: Pin P1B Shutdown State Control bits
00 = Drive pin P1B to ‘0’
01 = Drive pin P1B to ‘1’
1x = Pin P1B tri-state
Note 1: If CMSYNC is enabled, the shutdown will be delayed by Timer1.
Note 1: The auto-shutdown condition is a level-
based signal, not an edge-based signal.
As long as the level is present, the auto-
shutdown will persist.
2: Writing to the ECCPASE bit is disabled
while an auto-shutdown condition
persists.
3: Once the auto-shutdown condition has
been removed and the PWM restarted
(either through firmware or auto-restart)
the PWM signal will always restart at the
beginning of the next PWM period.
