Reg3_voltage

b00000000

This register is mapped to the register address

0h+Reg1_select, if gioX_iosf=5 or 6 (Vselect input), and

input = 1, This feature allows voltage switching of a

predefined regulator with just one GPIO input

0 ..FFh : Selects voltage, ilimit, ON or frequ. Bits of LDO or

DCDC
