Register 4082h LDO9 SLEEP Control
DESCRIPTION
LDO9 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 LDO9 is assigned to a Hardware Enable Input, then
codes 001-101 select in which timeslot the regulator
enters its SLEEP condition.
LDO9 SLEEP Operating Mode
0 = Normal mode
