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.
