Action to take on DC-DC4 fault (as well as
generating an interrupt):
00 = ignore
01 = shut down converter
10 = shut down system
11 = reserved (shut down system)
Reset by state machine. Default held in metal
mask.
Time slot for DC-DC4 start-up
0000 = Disabled (do not start up)
0001 = Start-up in time slot 1
… (total 14 slots available)
1110 = Start-up in time slot 14
1111 = Start-up on entering ACTIVE
Reset by state machine. Default held in metal
mask.
Time slot for DC-DC4 shutdown.
0000 = Shut down on entering OFF
0001 = Shutdown in time slot 1
…. (total 14 slots available)
