ENSEL1
When VSEL = High, it is used to gate the EN pin of the step-down converter. This makes
the step-down converter can enable/disable by I²C and Software.
When EN pin = High and this bit = 1, step-down converter can be enabled. Otherwise,
step-down converter would be disabled.
0 : Disable (even if EN=High, step-down converter still cannot be enabled.)
1 : Enable
VoutSEL1[6:0]
When VSEL = High, it is used to set Vout voltage level.
Vout voltage level = (303.125mV + 3.125m V x VoutSEL1[6:0]) x 2 ^ (0x1C.VOUT_BANK1
[1:0])

ENSEL0
When VSEL = Low, it is used to gate the EN pin of the step-down converter. This makes
the step-down converter can enable/disable by I²C and Software.
When EN pin = High and this bit = 1, step-down converter can be enabled. Otherwise,
step-down converter would be disabled.
0 : Disable (even if EN=High, step-down converter still cannot be enabled.)
1 : Enable
VoutSEL0[6:0]
When VSEL = Low, it is used to set Vout voltage level.
Vout voltage level = (303.125mV + 3.125m V x VoutSEL0[6:0]) x 2 ^ (0x1D.VOUT_BANK0
[1:0])
