Requirements
************

The temperature register always stores a 12 bit two's complement data,
giving a temperature resolution of 0.0625 °C. P3T1755DP can be configured
for different operation conditions: continuous conversion, one-shot mode
or shutdown mode. The device supports 2-wire serial I3C (up to 12.5 MHz)
and I²C (up to 3.4 MHz) as communication interface.
