ECCP1AS: ENHANCED CAPTURE/COMPARE/PWM AUTO-SHUTDOWN

CONTROL REGISTER

R/W-0

ECCPASE

ECCPAS2 ECCPAS1 ECCPAS0 PSSAC1

PSSAC0 PSSBD1(1) PSSBD0(1)

bit 7

bit 0

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

ECCPAS2:ECCPAS0: ECCP Auto-Shutdown Source Select bits

111

= FLT0 or Comparator 1 or Comparator 2

110

= FLT0 or Comparator 2

101

= FLT0 or Comparator 1

100

=FLT0

011

= Either Comparator 1 or 2

010

= Comparator 2 output

001

= Comparator 1 output

000

= Auto-shutdown is disabled

bit 3-2

PSSAC1:PSSAC0: Pins A and C Shutdown State Control bits

= Pins A and C are tri-state (40/44-pin devices);

PWM output is tri-state (28-pin devices)

= Drive Pins A and C to ‘1’

= Drive Pins A and C to ‘0’

bit 1-0

PSSBD1:PSSBD0: Pins B and D Shutdown State Control bits(1)

= Pins B and D tri-state

= Drive Pins B and D to ‘1’

= Drive Pins B and D to ‘0’

Note 1: Reserved on 28-pin devices; maintain these bits clear.

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
