LDO1 SLEEP
Control
000 = SLEEP voltage / operating
mode transition in Timeslot 5
001 = Disable in Timeslot 5
010 = Disable in Timeslot 4
011 = Disable in Timeslot 3
100 = Disable in Timeslot 2
101 = Disable in Timeslot 1
110 = SLEEP voltage / operating
mode transition in Timeslot 3
111 = SLEEP voltage / operating
mode transition in Timeslot 1
If LDO1 is assigned to a Hardware
Enable Input, then codes 001-101
select in which timeslot the regulator
enters its SLEEP condition.
