ECCPASE ECCPAS2 ECCPAS1 ECCPAS0 PSSAC1 PSSAC0 PSSBD1 PSSBD0
bit 7 bit 0
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
bit 7 ECCPASE: ECCP Auto-Shutdown Event Status bit
1 = A shutdown event has occurred; ECCP outputs are in shutdown state
0 = ECCP outputs are operating
bit 6-4 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

100 =VIL on INT pin
101 =V
IL on INT pin or Comparator change
110 =V
IL on INT pin

111 =VIL on INT pin or Comparator change
bit 3-2 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
bit 1-0 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.
