DESCRIPTION
LDO11 ON Voltage select
0.80V to 1.55V in 50mV steps
0h = 0.80V
1h = 0.85V
2h = 0.90V
…
Eh = 1.50V
Fh = 1.55V
LDO11 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 LDO11 is assigned to a Hardware
Enable Input, then codes 001-101
select in which timeslot the regulator
enters its SLEEP condition.
