The sensor has a fix I2C address 0x44. The resolution
is fixed to 14bit (ref. Missing feature).

Missing feature:
- Accessing non-volatile memory: Custom board has no
possibility to control voltage supply of sensor. Thus,
we cannot send the necessary control commands within
the first 10ms after power-on.

sensor selector can selector a speific thermal sensor as temperature input.
The sampling register is used to obtain the temperature in real time, the
control register GATE field is used to set the threshold of high or low
temperature, when the input temperature is higher than the high temperature
threshold or lower than the low temperature threshold, an interrupt will
