Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
u = Bit is unchanged
‘1’ = Bit is set
x = Bit is unknown
‘0’ = Bit is cleared
bit 7
CCPxASE: CCPx Auto-Shutdown Event Status bit
1= A shutdown event has occurred; CCPx outputs are in shutdown state
0= CCPx outputs are operating
bit 6-4
CCPxAS<2:0>: CCPx Auto-Shutdown Source Select bits
000= Auto-shutdown is disabled
001= Comparator C1 output high(1)
010= Comparator C3 output high(1)
011= Either Comparator C1 or C3 high(1)
100= VIL on INT pin
101= VIL on INT pin or Comparator C1 high(1)
110= VIL on INT pin or Comparator C3 high(1)
111= VIL on INT pin or Comparator C1 or Comparator C3 high(1)
bit 3-2
bit 1-0
PSSxAC<1:0>: Pins PxA and PxC Shutdown State Control bits
00= Drive pins PxA and PxC to ‘0’
01= Drive pins PxA and PxC to ‘1’
1x= Pins PxA and PxC tri-state
PSSxBD<1:0>: Pins PxB and PxD Shutdown State Control bits
00= Drive pins PxB and PxD to ‘0’
01= Drive pins PxB and PxD to ‘1’
1x= Pins PxB and PxD tri-state
Note 1: If CxSYNC is enabled, the shutdown will be delayed by Timer1.
