CCPxAS: CCPX AUTO-SHUTDOWN CONTROL REGISTER

R/W-0/0

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

111 =VIL on INT pin or Comparator C1 or Comparator C2 high(1, 2)

110 =VIL on INT pin or Comparator C2 high(1, 2)

101 =VIL on INT pin or Comparator C1 high(1)

100 =VIL on INT pin

011 = Either Comparator C1 or C2 high(1, 2)

010 = Comparator C2 output high(1, 2)

001 = Comparator C1 output high(1)

000 = Auto-shutdown is disabled

bit 3-2

PSSxAC<1:0>:

Pins PxA and PxC Shutdown State Control bits

1x = Pins PxA and PxC tri-state

01 = Drive pins PxA and PxC to ‘1’

00 = Drive pins PxA and PxC to ‘0’

bit 1-0

PSSxBD<1:0>:

Pins PxB and PxD Shutdown State Control bits

1x = Pins PxB and PxD tri-state

01 = Drive pins PxB and PxD to ‘1’

00 = Drive pins PxB and PxD to ‘0’

Note 1:

If CxSYNC is enabled, the shutdown will be delayed by Timer1.

For PIC16F1946/47 devices in ECCP3 mode, CCPxAS uses C3 instead of C2.
