Bit Description

sd3_frequ

Selects between high and low frequency

dependent on sd3_fsel

0 : 2MHz if sd3_fsel=0, 3MHz if sd3_fsel=1

1 : 3MHz if sd3_fsel=0, 4MHz if sd3_fsel=1

6:0

sd3_vsel

b0000000

The voltage select bits set the DC/DC output voltage

level and power the DC/DC converter down.

00h : DC/DC powered down

01h-40h : V_SD3=0.6V+sd3_vsel*12.5mV

41h-70h : V_SD3=1.4V+(sd3_vsel-40h)*25mV

71h-7Fh : V_SD3=2.6V+(sd3_vsel-70h)*50mV

Bit Description

sd4_low_p

ower

0RW

Controls low power mode for sd4

0 : Normal mode

1 : Low power mode. Reduced current capability only 1

phase enabled and reduced output current on that phase

6:0

sd4_vsel

b0000000

The voltage select bits set the DC/DC output voltage

level and power the DC/DC converter down. (0.6..1.5V)

00h : DC/DC powered down

01h-5Ah : V_SD4=0.6V+sd4_vsel*10mV

5Ah-7Fh : NA
