Name

Base

Default

PMU CVDD1

2-wire serial

00h

CVDD1 DC/DC Buck Regulator Control Register

Offset: 17h-3

This is an extended register and needs to be enabled by writing 011b to Reg. 18h first.

This register is reset at a DVDD-POR.

Bit Description

SKIP_OFF_CVDD1

R/W

Disables pulse skip mode

0: 170mA current force / pulse skip mode enabled

1: current force / pulse skip mode disabled (only ON without

load)

PROG_CVDD1

R/W

Enables settings either selected by external pin (VPRGx) or

settings stored in the 17h-3 register

0: VPRGx pins controlled

1: Register controlled

5:0

VSEL_CVDD1

00000

R/W

The voltage select bits set the DC/DC output voltage level and

power the DC/DC converter down.

00000: DC/DC powered down

01h until 38h in 50mV steps

CVDD1=0.6V+VSEL_CVDD1*50mV

(0.65V until 3.4V)

38h until 3Fh = 3.4V (no change)
