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] controls 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
Note - Maximum output voltage selection in 4MHz
switching mode is 48h (1.4V).
