Offset Register
Offset errors may be introduced into the remote temperature
measurement by clock noise or by the thermal diode being
located away from the hot spot. To achieve the specified
accuracy on this channel, these offsets must be removed.
The offset value is stored as a 10-bit, twos complement value in
Registers 0x11 (high byte) and 0x12 (low byte, left justified).
Only the upper 2 bits of Register 0x12 are used. The MSB of
Register 0x11 is the sign bit. The minimum offset that can be
programmed is −128°C, and the maximum is +127.75°C. The
value in the offset register is added to the measured value of the
remote temperature.
The offset register powers up with a default value of 0°C and
has no effect unless the user writes a different value to it.
