bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

ECCPASE: ECCP Auto-Shutdown Event Status bit

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

= ECCP outputs are operating

bit 6-4

ECCPAS<2:0>: ECCP Auto-shutdown Source Select bits

000

= Auto-Shutdown is disabled

001

= Comparator output change

010

= Auto-Shutdown is disabled

011

= Comparator output change(1)

100

=VIL on INT pin

101

=VIL on INT pin or Comparator change

110

=VIL on INT pin(1)

111

=VIL on INT pin or Comparator change

bit 3-2

PSSAC<1:0>: Pin P1A Shutdown State Control bits

= Drive pin P1A to ‘0’

= Drive pin P1A to ‘1’

= Pin P1A tri-state

bit 1-0

PSSBD<1:0>: Pin P1B Shutdown State Control bits

= Drive pin P1B to ‘0’

= Drive pin P1B to ‘1’

= Pin P1B tri-state

Note 1:

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

Note 1: The auto-shutdown condition is a level-

based signal, not an edge-based signal.

As long as the level is present, the auto-

shutdown will persist.

2: Writing to the ECCPASE 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.
