MSB Byte

LSB Byte

The temperature register contains the digitally converted temperature value. It consists of 2 bytes and

can be converted according to the following formula:

Positive values= |Value| / LSB

Negative values= Complement( |Value| / LSB ) + 1

E75°C

75°𝐶 / 0.0625°𝐶 = 1200 = 𝐵𝑖𝑛𝑎𝑟𝑦 0100 1011 0000 = 𝐻𝑒𝑥 4𝐵0

Example -40°C

|−40°𝐶| / 0.0625°𝐶 + 1 = 640 + 1 = 𝐵𝑖𝑛𝑎𝑟𝑦 0010 1000 0000 + 1 = 1101 0111 1111 + 1 =
1101 10000 0000 = 𝐻𝑒𝑥 𝐷80
