VSET1

R/W

Secondary Output Voltage Selection. Valid when VSEL is driven

high. See the Output Voltage Programming section for more

information.

REG3

0x32

[7]

R/W

Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit

to 0 to disable the regulator.

PHASE

R/W

Regulator Phase Control. Set bit to 1 for the regulator to operate

180° out of phase with the oscillator, clear bit to 0 for the

regulator to operate in phase with the oscillator.

nFLTMSK

R/W

Regulator Fault Mask Control. Set bit to 1 enable fault-interrupts,

clear bit to 0 to disable fault-interrupts.

REG3

0x32
