PIC18(L)F2X/4XK22

ECCPxAS: CCPX AUTO-SHUTDOWN CONTROL REGISTER

R/W-0

CCPxASE

CCPxAS<2:0>

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

if PxRSEN = 1;

1 = An Auto-shutdown event occurred; CCPxASE bit will automatically clear when event goes away;

CCPx outputs in shutdown state

0 = CCPx outputs are operating

if PxRSEN = 0;

1 = An Auto-shutdown event occurred; bit must be cleared in software to restart PWM;

CCPx outputs in shutdown state

0 = CCPx outputs are operating

bit 6-4

CCxPAS<2:0>: CCPx Auto-Shutdown Source Select bits (1)

000 = Auto-shutdown is disabled

001 = Comparator C1 – output high will cause shutdown event

010 = Comparator C2 – output high will cause shutdown event

011 = Either Comparator C1 or C2 – output high will cause shutdown event

100 = FLT0 pin - low level will cause shutdown event

101 = FLT0 pin or Comparator C1 – low level will cause shutdown event

110 = FLT0 pin or Comparator C2 – low level will cause shutdown event

111 = FLT0 pin or Comparators C1 or C2 – low level will cause shutdown event

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 C1SYNC or C2SYNC bits in the CM2CON1 register are enabled, the shutdown will be delayed by

Timer1.
