Description
Local temperature offset.
Allows a twos complement offset value to be
automatically added to or subtracted from the local
temperature reading. LSB value = 0.5°C.

Description
Remote 2 temperature offset.
Allows a twos complement offset value to be
automatically added to or subtracted from the
Remote 2 temperature reading. This is to
compensate for any inherent system offsets
such as PCB trace resistance. LSB value = 0.5°C.

Unused. Do not write to these bits.
Description
Remote 1 temperature offset.
Allows a twos complement offset value to
be automatically added to or subtracted
from the Remote 1 temperature reading.
This is to compensate for any inherent
system offsets such as PCB trace resistance.
LSB value = 0.5°C.
Description
XNOR tree test enable register.
If the XEN bit is set to 1, the device enters
the XNOR tree test mode. Clearing the bit
removes the device from the XNOR tree test
mode.
