Temperature limit register format
The high and low limit registers have the same format as the temperature register with the
integer portion of the two's complement value stored in the high byte and the fractional
portion in the low byte. These registers are read-write.
Note that the high limit defaults to 85 °C.
Temperature limit register (two’s complement format)
Temperature examples
The table below shows several examples of how the data is arranged in the high and low
byte pairs used for the temperature and limit registers.
Temperature examples (two’s complement format)
The maximum and minimum values for the temperature registers are 127.9375 (7F:F0h,
high byte : low byte) and –64 (C0:00h), respectively. This also applies to the high and low
limit registers.
