DC-DC2 ON Voltage select
DC2_ON_VSEL[6:0] selects the DC-DC2 output
voltage from 0.6V to 1.8V in 12.5mV steps.
DC2_ON_VSEL[6:2] also exist in DBE/OTP memory,
controlling the voltage in 50mV steps.
DC2_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
