The temperature register contains the digitally converted temperature value and can be read by

setting the index pointer to the TVAL register (0x0).

Two consecutive bytes must be read to obtain the complete temperature value. The MSB byte (Bits

D15…D8) is transmitted upon the first read access and the LSB byte (Bits D7…D0) is transmitted after

the second read access

. The least significant bits D3…D0 are set to 0.

A temperature value is represented as a two complement value in order to cover also negative values.

After power up, the temperature value is read as 0°C until the first conversion has been completed.

One LSB corresponds to 0.0625°C.

The binary values can be calculated according to the following formulas:

Positive values:

|Value| / LSB

Negative values:

Complement (|Value| / LSB) + 1
