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 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

DC3_ON_VSE

L [1:0]

DC3 ON Voltage select

DC3_ON_VSEL [6:0] selects the DC3 output voltage

from 0.85V to 3.4V in 25mV steps.

See DC3_ON_VSEL [6:2] for definition.
