CCPxASE CCPxAS<2:0> PSSxAC<1:0> PSSxBD<1:0>
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘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 C2 output high
(1)
011 = Either Comparator C1 or C2 high
(1)
100 =VIL on FLT0 pin
101 =V
IL on FLT0 pin or Comparator C1 high
(1)
110 =VIL on FLT0 pin or Comparator C2 high
(1)
111 =VIL on FLT0 pin or Comparator C1 or Comparator C2 high
(1)
bit 3-2 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
bit 1-0 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.
