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.
Unused. Do not write to these bits.
Remote 1 temperature offset.
Allows a temperature offset to be automatically applied to the Remote
Temperature 1 channel measurement. Bit 1 of Configuration Register
5 (0x7C) determines the range and resolution of this register.
Local temperature offset.
Allows a temperature offset to be automatically applied to the local
temperature measurement. Bit 1 of Configuration Register 5 (0x7C)
determines the range and resolution of this register.
Remote 2 temperature offset.
Allows a temperature offset to be automatically applied to the Remote
Temperature 2 channel measurement. Bit 1 of Configuration Register
5 (0x7C) determines the range and resolution of this register.
