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

= A shutdown event has occurred; CCPx outputs are in shutdown state

= CCPx outputs are operating

bit 6-4

CCxPAS<2:0>: CCPx Auto-Shutdown Source Select bits

000

= Auto-shutdown is disabled

001

= Comparator C1 output low(1)

010

= Comparator C2 output low(1)

011

= Either Comparator C1 or C2 low(1)

100

=VIL on INT pin

101

=VIL on INT pin or Comparator C1 low(1)

110

=VIL on INT pin or Comparator C2 low(1)

111

=VIL on INT pin or Comparator C1 or Comparator C2 low(1)

bit 3-2

PSSxACx: Pins P1A and P1C Shutdown State Control bits

= Drive pins P1A and P1C to ‘0’

= Drive pins P1A and P1C to ‘1’

= Pins P1A and P1C tri-state

bit 1-0

PSSxBDx: Pins P1B and P1D Shutdown State Control bits

= Drive pins P1B and P1D to ‘0’

= Drive pins P1B and P1D to ‘1’

= Pins P1B and P1D tri-state

Note 1:

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

Note 1: The

auto-shutdown

condition

level-based signal, not an edge-based

signal. As long as the level is present, the

auto-shutdown will persist.

2: Writing to the CCPxASE bit is disabled

while

auto-shutdown

condition

persists.

3: Once the auto-shutdown condition has

been removed and the PWM restarted

(either through firmware or auto-restart)

the PWM signal will always restart at the

beginning of the next PWM period.
