Hi@rlaxortn

I have already answered all of these in your previous questions.

if i set 0x15, is that mean is 1.5V?， the answer is yes,

But this value is not set randomly.

I suggest you read Chapter 85 Temperature Sensor in the data sheet .

Just to correct myself, there were some errors in my answer.

The data format used was S11.4.

Therefore, the actual value = original 16-bit signed number ÷ 16

For example:

1.0x15 = 21 / 16 = 1.3125V

2.0x35 = 53 / 16 = 3.3125V

3.0x50 = 80 / 16 = 5V
