DC-DC1 ON Voltage select
DC1_ON_VSEL[6:0] selects the DC-
DC1 output voltage from 0.6V to 1.8V in
12.5mV steps.
DC1_ON_VSEL[6:2] also exist in
ICE/OTP memory, controlling the
voltage in 50mV steps.
DC1_ON_VSEL[6:0] is coded as
follows:
00h to 08h = 0.6V
09h = 0.6125V
…
48h = 1.4V (see note)
…
67h = 1.7875V
68h to 7Fh = 1.8V
Note - Maximum output voltage
selection in 4MHz switching mode is
48h (1.4V).

DC-DC1 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 DC-DC1 is assigned to a Hardware
Enable Input, then codes 001-101 select
in which timeslot the converter enters its
SLEEP condition.
