I set DC2DC register address 0x21 value from 0x97 to 0x91 (VR12.0 mode),but the output voltage don't change from 1V to 0.97V?
please provide the set sequece to change output voltage via smbus, and need to save the set value to the dc2dc controller.(when next power up the output voltage value is the 0.97V not 1V)
