Read acquired temperature
To read the 2 bytes temperature register, the I2C master must send a Pointer Set
Configuration Register Write frame followed by a 2-byte read frame (see Figure 15).
This operation is managed by calling the I2C_SS_BufferRead(unit8_t* pBuffer,
unit16_t ReadAddr, unit8_t NumberByteToRead)
function.
Figure 15.
Typical pointer set followed by a READ for 2-byte register

Temperature format
Table 8 shows the relationship between the output digital data and the external temperature
for 9 to 12-bit resolution. The left-most bit in the output data stream controls temperature
polarity information for each conversion. If the sign bit is '0', the temperature is positive and
of the sign bit is '1', the temperature is negative.
