Notes:
1.
2.
The address for the device in the 2-wire mode is 001101X (binary) with the last bit selectable.
In the two-wire interface mode, the CSBIWL pin indicates the final bit of the chip address.
3.
In 2-wire mode the LATI2S pin should be tied to either DGND or DVSS to avoid noise toggling the interface into 3-wire
mode.
