Description
XOR Tree Test Enable Register
If the XEN bit is set to 1, the device enters the XOR Tree Test Mode. Clearing the bit
removes the device from the XOR Test Mode.
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 = 0.25°C.
Description
Local Temperature Offset
Allows a twos complement offset value to be automatically added to or subtracted from
the local temperature reading. LSB value = 0.25°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 off-
sets such as PCB trace resistance. LSB value = 0.25°C.
