Temperature Value Register
This 16-bit read only register stores the temperature measured
by the internal temperature sensor. The temperature is stored in
twos complement format with the MSB being the temperature
sign bit. When reading from this register, the eight MSBs (Bit
D15 to Bit D8) are read first and then the eight LSBs (Bit D7 to
Bit D0) are read. The control register settings are the default
settings on power up.
Configuration Register
This 8-bit read/write register stores various configuration modes
for the ADT75. These modes are shutdown, overtemperature
interrupt, one-shot, SMBus alert function enable, OS/ALERT
pin polarity, and overtemperature fault queues. See Table 10.
