Bits Name
R/W Description
7
Timing
R/W This bit specifies when the flag is set.
0 = after debounce.
1 = immediately.
6
Resolve issue
R/W This bit specifies when the part is reenabled after the fault that triggered the flag has been resolved.
0 = reenable after the power supply reenable time set in Register 0x0E[1:0].
1 = remain disabled; power supply must be restarted to reenable.
[5:4] Action
R/W These bits specify the action that the part takes in response to the flag.
Bit 5
Bit 4
Action
0
0
Ignore flag completely
0
