6.5 Temperature Measurement Machine
The temperature data format is 8-bit two - complement for sensor 1 and 9-bit two - complement for
sensor 2/3. The 8-bit temperature data can be obtained by reading the CR [27h]. The 9-bit
temperature data can be obtained by reading the 8 MSBs from the Bank1/2 CR [50h] and the LSB
from the Bank1/2 CR [51h] bit 7. The format of the temperature data is show in Table 1.
