DC1_ON_VSE

L [6:2]

0_0000

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).
