DC3_ON_VS
EL [1:0]
00
DC3_ON_VSEL[6:0] selects the DC-
DC3 output voltage from 0.85V to
3.4V in 25mV steps.
DC3_ON_VSEL[6:2] also exist in
ICE/OTP memory, controlling the
voltage in 100mV steps.
DC3_ON_VSEL[6:0] is coded as
follows:
00h = 0.85V
01h = 0.875V
…
65h = 3.375V
66h to 7Fh = 3.4V

DC-DC3 SLEEP Voltage select
0.85V to 3.4V in 25mV steps
00h = 0.85V
01h = 0.875V
…
65h = 3.375V
66h to 7Fh = 3.4V

DC4_SLV
0
DC-DC4 Slave Mode select
0 = Disabled
1 = Enabled
DC4_SLV = 1, then DC-DC4 is a
slave to DC-DC3, and both
converters are controlled by the DC-
DC3 registers.
This field can only be written to by
loading configuration settings from
OTP/ICE. In all other cases, this field
is Read Only.
