Warning Threshold Registers
Default value for both bytes
Serial address
Bytes addresses
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.
