000

LDO6 SLEEP Slot select

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 LDO6 is assigned to a Hardware Enable Input, then

codes 001-101 select in which timeslot the regulator

enters its SLEEP condition.
