5.3.5.1 Sensor Trigger Function
The Sensor Trigger function is used to reset the IPSO min/max values as well as to control the Calibration process.

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 DIO inputs and all bits should be written as 0.
5.3.6 DIO Input Circuitry
The DIO input circuitry shares the output circuitry. The internal processor drives the Output Control signal to turn on
the output driver which will force the output LOW. When the state of the DIO input signal is to be read the processor
applies 3.0 V
to the Input Bias signal and reads the level detected at the Input Sense. If the output is inactive, an
DC
external signal may be used to force the input level LOW. A diode protects external positive voltages, allowing the
Output driver to activate loads greater than the internal 3.3 V
