CCPxASE: CCPx Auto-Shutdown Event Status bit
1 = A shutdown event has occurred; CCPx outputs are in shutdown state
0 = CCPx outputs are operating
CCxPAS<2:0>: CCPx Auto-Shutdown Source Select bits
000 = Auto-shutdown is disabled
001 = Comparator C1 output low⁽¹⁾
010 = Comparator C2 output low⁽¹⁾
011 = Either Comparator C1 or C2 low⁽¹⁾
100 = VIL on INT pin
101 = VIL on INT pin or Comparator C1 low⁽¹⁾
110 = VIL on INT pin or Comparator C2 low⁽¹⁾
111 = VIL on INT pin or Comparator C1 or Comparator C2 low⁽¹⁾
PSSxACx: Pins P1A and P1C Shutdown State Control bits
00 = Drive pins P1A and P1C to ‘0’
01 = Drive pins P1A and P1C to ‘1’
1x = Pins P1A and P1C tri-state
PSSxBDx: Pins P1B and P1D Shutdown State Control bits
00 = Drive pins P1B and P1D to ‘0’
01 = Drive pins P1B and P1D to ‘1’
1x = Pins P1B and P1D tri-state
Note 1: If CxSYNC 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 CCPxASE 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.
