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
ECCPAS2:ECCPAS0: ECCP Auto-Shutdown Source Select bits
111 = FLT0 or Comparator 1 or Comparator 2
110 = FLT0 or Comparator 2
101 = FLT0 or Comparator 1
100 = FLT0
011 = Either Comparator 1 or 2
010 = Comparator 2 output
001 = Comparator 1 output
000 = Auto-shutdown is disabled
PSSAC1:PSSAC0: Pins A and C Shutdown State Control bits
1x = Pins A and C are tri-state (40/44-pin devices);
01 = Drive Pins A and C to ‘1’
00 = Drive Pins A and C to ‘0’
PSSBD1:PSSBD0: Pins B and D Shutdown State Control bits
1x = Pins B and D tri-state
01 = Drive Pins B and D to ‘1’
00 = Drive Pins B and D to ‘0’
