Start
Setting the Reset Min/Max bit to 1 will reset the Min/Max values recorded by the IPSO process. No User
Calibration process is supported on the Digital inputs and all configuration bits should be written as 0.

Process Input
The Process Input interface provides single-ended voltage and current loop inputs. The Sensor Configuration and
Sensor Device fields may be written to provide control of the overall function of the channel and the signal types
used.
