Bit Description

7:6

dvm_time_sd4

b00

Time steps of DVM voltage change of SD4

If voltage of step Down is changed during operation

(sdx_vsel)

voltage is de/increased by single steps 10mV

0 : 0 usec, immediate change (no DVM)

1 : 1 usec time delay between steps

2 : 2 usec time delay between steps

3 : 8 usec time delay between steps

5:4

dvm_time_sd1

b00

Time steps of DVM voltage change of SD1

If voltage of step Down is changed during operation

(sdx_vsel)

voltage is de/increased by single steps 12.5/25/50mV

0 : 0 usec, immediate change (no DVM)

1 : 4 usec time delay between steps

2 : 8 usec time delay between steps

3 : 16 usec time delay between steps

3sd3_slave

RW_SM

Enables slave mode of SD3

0 : Normal mode of SD3

1 : SD3 is slave of SD2.

sd3_fsel

RW_SM

Selects between high and low frequency range

0 : 2 or 3MHz frequency (selctable by sd3_frequ)

1 : 3 or 4MHz frequency (selctable by sd3_frequ)

sd2_fsel

RW_SM

Selects between high and low frequency range

0 : 2 or 3MHz frequency (selctable by sd2_frequ)

1 : 3 or 4MHz frequency (selctable by sd2_frequ)

0sd2_slave

RW_SM

Enables slave mode of SD2

0 : Normal mode of SD2

1 : SD2 is slave of SD1
