REGISTER 23-4:

CCPxAS: CCPX AUTO-SHUTDOWN CONTROL REGISTER

R/W-0/0

CCPxASE

CCPxAS2

CCPxAS1

CCPxAS0

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

CCPxAS2:

CCPx Auto-Shutdown Source 2 Select bit

1 = Auto-shutdown 2 source is enabled, V

on INT pin

0 = Auto-shutdown 2 source is disabled

bit 5

CCPxAS1:

CCPx Auto-Shutdown Source 1 Select bit

1 = Auto-shutdown 1 source is enabled, async_CxOUT

(1),(2)

output low

0 = Auto-shutdown 1 source is disabled

bit 4

CCPxAS0:

CCPx Auto-Shutdown Source 0 Select bit

1 = Auto-shutdown 0 source is enabled, async_C1OUT

(1)

output low

0 = Auto-shutdown 0 source is disabled

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.

async_CxOUT = async_C2OUT (for CCP1 and CCP2)

async_CxOUT = async_C3OUT (for CCP3)
