Function

[7]

When the voltage drop to 2.62V then this signal

will be activated. Because when the voltage below

2.62V the ADC can not normal operation.

[6]

The ADC analog circuit detects the DXP and DXN

pins are short together.

Function

[7]

Select SMBus slave address. 0: slave address is

7’h48, 1: slave address is 7’h4A. The SMBus slave

address can determine from this register bit and

also can pull up or pull down the ALERT# pin.

When pull up ALERT# pin the slave address is

7’h48, otherwise it is 7’h4A.

[6:4]

Reserved. Not implemented.

[3]

Software reset the control logic.

Reserved. Not implemented. Bit [2] always one.

[0]

ADC free run mode, i.e., the ADC operation does

not restrict by conversion rate.
