Setting the Reset Min/Max bit to 1 will reset the Min/Max values recorded by the IPSO process. No
user calibration is supported in the temperature sensor and all configuration bits should be written
as 0.

Discrete I/O Interface
The SP-006 supports a DIO Interface that provides 2 discrete inputs that are hardwired to the outputs. These may be
used to detect the state of external switches (output off) or to monitor the state of the outputs.
