ECCPASE: ECCP Auto-Shutdown Event Status bit
1 = A shutdown event has occurred; ECCP outputs are in a shutdown state
0 = ECCP outputs are operating
ECCPAS<2:0>: ECCP Auto-Shutdown Source Select bits
111 = VIL on FLT0 pin, or either C1OUT or C2OUT is high
110 = VIL on FLT0 pin, or C2OUT comparator output is high
101 = VIL on FLT0 pin, or C1OUT comparator output is high
100 = VIL on FLT0 pin
011 = Either C1OUT or C2OUT is high
010 = C2OUT comparator output is high
001 = C1OUT comparator output is high
000 = Auto-shutdown is disabled
PSSAC<1:0>: PxA and PxC Pins Shutdown State Control bits
1x = P1A and P1C pins tri-state
01 = Drive pins P1A and P1C to ‘1’
00 = Drive pins P1A and P1C to ‘0’
PSSBD<1:0>: PxB and PxD Pins Shutdown State Control bits
1x = P1B and P1D pins tri-state
01 = Drive pins, P1B and P1D, to ‘1’
00 = Drive pins, P1B and P1D, to ‘0’
Note 1: This register is implemented only on PIC24FXXKL40X/30X devices.
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 an 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.
