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

ECCPAS2: ECCP Auto-Shutdown bit 2

= RB0 (INT) pin low level (‘0’) causes shutdown

RB0 (INT) pin has no effect on ECCP

bit 5

Unimplemented: Read as ‘0’

bit 4

ECCPAS0: ECCP Auto-Shutdown bit ‘0’

= RB4 pin low level (‘0’) causes shutdown

= RB4 pin has no effect on ECCP

bit 3-2

PSSACn: 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

PSSBDn: 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: 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.
