Offset Cal Enable <ch3..ch0>

Shunt Cal Enable <3..0>

Controls the shunt calibration switch for each of the four channels. A logic 1 in any bit closes the 
switch for the respective channel, while a logic 0 opens the switch.

Half Bridge Enable <3..0>

Controls the half bridge completion option for each channel. Enabling half bridge completion for a 
channel disconnects the negative signal input pin from the rest of the circuit, and uses an internal 
voltage equal to the midpoint of the excitation voltage as the negative input to the rest of the circuit. 
A logic 1 in any bit enables half bridge completion for the respective channel, while a logic 0 
disables it. 

Excitation

Sets the excitation voltage setting. All channels share the same excitation voltage.

0b000 = 0

2.5 V 

The 

OCLK

 pin is used as the 

oversample clock source.

0b001 = 1

3.3 V

The 12.8 MHz internal clock is 
used as the clock source and 
this 12.8 MHz is driven onto 
the 

OCLK

 pin.

0b010 = 2

5.0 V

The internal clock is used but 
not driven onto 

OCLK

 pin. 

Currently, this is the required 
clock setting.
