BO
Burnout Current Enable Bit.
Set by user to enable both transducer burnout current sources in the primary ADC signal paths.
Cleared by user to disable both transducer burnout current sources.
5
ADC1IC
Auxiliary ADC Current Correction Bit.
Set by user to allow scaling of the Auxiliary ADC by an internal current source calibration word.

I2PIN
*
Current Source-2 Pin Select Bit.
Set by user to enable current source-2 (200
μA) to external Pin 3 (P1.2/DAC/IEXC1).
Cleared by user to enable current source-2 (200
μA) to external Pin 4 (P1.3/AIN5/IEXC2).
2
I1PIN
*
Current Source-1 Pin Select Bit.
Set by user to enable current source-1 (200
μA) to external Pin 4 (P1.3/AIN5/IEXC2).
Cleared by user to enable current source-1 (200
μA) to external Pin 3 (P1.2/DAC/IEXC1).

I1EN
Current Source-1 Enable Bit.
Set by user to turn on excitation current source-1 (200
μA).
Cleared by user to turn off excitation current source-1 (200
μA).
*Both current sources can be enabled to the same external pin, yielding a 400
μA current source.
