Bit Description

7sd1_frequ

Selects between high and low frequency

0 : 1 MHz if sd1_fsel=0, 2MHz if sd1_fsel=1

1 : 3 MHz if sd1_fsel=0, 4MHz if sd1_fsel=1

6:0

sd1_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_SD1=0.6V+sd1_vsel*12.5mV

41h-70h : V_SD1=1.4V+(sd1_vsel-40h)*25mV

71h-7Fh : V_SD1=2.6V+(sd1_vsel-70h)*50mV

Addr:02h

0 : 100mA operating range

1 : 200mA operating range

5:0

ldo1_vsel

b000000

The voltage select bits set the LDO output voltage

00h-2Ah : V_LDO1=1.2V+ldo1_vsel*50mV
