This register provides a means to offset readings from remote diodes to compensate for errors due to system noise or series
resistance. It may also be used to compensate for a difference in temperature between the remote diode and the
temperature of interest once that is characterized by the user. It is in 2’s Complement format with 0.25 degree resolution.
The range is -32 to +31.75
°C and is described in Table 10:
