7.2.3
These registers become read only when the Lock bit is set. Any further attempts to write to these
registers shall have no effect.
Offset Register Ambient only applies to the internal (ambient) temperature reading. This register
contains a 2's complement value, which is added (or subtracted if the number is negative) to the
ambient temperature reading. The default value in the offset register is zero, so initially zero is always
added to the temperature reading.
Offset Register 2 only applies to the remote diode 2 temperature reading. This register contains a
2's complement value, which is added (or subtracted if the number is negative) to external temperature
reading 2. The default value in the offset register is zero, so initially zero is always added to the
temperature reading.
Offset Register 1 only applies to the remote diode 1 temperature reading. This register contains a
2's complement value, which is added (or subtracted if the number is negative) to the external
temperature reading 1 reading. The default value in the offset register is zero, so initially zero is always
added to the temperature reading.
