Warning Threshold Registers

Default value for both bytes

Each LS bit of THIGHh represents one degree Celsius. THIGHl is not used, since all limit comparisons for temperature use
eight-bit values.
The eight bits of the high warning threshold value (THIGHh) are compared to the temperature result (TEMPh). WARN0 bit 7 is
set if Result > Threshold.

Each LS bit of TLOWh represents one degree Celsius. TLOWl is not used, since all limit comparisons for temperature use
eight-bit values.
The eight bits of the high warning threshold value (TLOWh) are compared to the temperature result (TEMPh). WARN0 bit 6 is
set if Result < Threshold.

Each LS bit of VHIGHh represents 25.6 mV and each LS bit of VHIGHl represents 0.1 mV. The sixteen-bit threshold value
(VHIGHh:VHIGHl) is compared to the sixteen bits value of the voltage result (VINh:VINl). WARN0 bit 5 is set if
Result > Threshold.

Each LS bit of VLOWh represents 25.6 mV and each LS bit of VLOWl represents 0.1 mV. The sixteen-bit threshold value
(VLOWh:VLOWl) is compared to the sixteen-bit value of the voltage result (VINh:VINl). WARN0 bit 4 is set if
Result < Threshold.
