DC-DC3 Error Action (Undervoltage)
00 = Ignore
01 = Shut down converter
10 = Shut down system (Device Reset)
11 = Reserved
Note that an Interrupt is always raised.
DC-DC3 Hardware Control Source
00 = Disabled
01 = Hardware Control 1
10 = Hardware Control 2
11 = Hardware Control 1 or 2
DC-DC3 Hardware Control Voltage select
0 = Set by DC3_ON_VSEL
1 = Set by DC3_SLP_VSEL
DC-DC3 Hardware Control Operating Mode
00 = Forced Continuous Conduction Mode
01 = Disabled
10 = LDO Mode
11 = Hysteretic Mode
DC-DC3 Overvoltage Protection
0 = Disabled
1 = Enabled
DC-DC3 ON Slot select
000 = Do not enable
001 = Enable in Timeslot 1
010 = Enable in Timeslot 2
011 = Enable in Timeslot 3
100 = Enable in Timeslot 4
101 = Enable in Timeslot 5
110 = Controlled by Hardware Enable 1
111 = Controlled by Hardware Enable 2
DC-DC3 ON Operating Mode
00 = Forced Continuous Conduction Mode
01 = Continuous / Discontinuous Conduction with
Pulse-Skipping
10 = LDO Mode
11 = Hysteretic Mode
DC-DC3 ON Voltage select
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 DBE/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
