Warning Threshold Registers
Default Value
Serial Address
Bytes Address
Each LSB of THIGHh represents one degree centigrade. This register is to be used in conjunction with THIGHl to yield a
sixteen-bit temperature value. The value in this register is uncalibrated. The nine MSbits of threshold value (THIGHh;THIGHl)
are compared, bit to bit, to the nine MSbits value of the temperature reading (TEMPh;TEMPl).. Warning bit Wx is set if Reading
> Threshold.

Bytes Address
Each LSB of TLOWh represents one degree centigrade. This register is to be used in conjunction with TLOWl to yield a
sixteen-bit temperature value. The value in this register is uncalibrated. The threshold value (THIGHh;THIGHl) is compared, bit
to bit, to the value of the temperature reading (TEMPh;TEMPl). Warning bit Wx is set if Reading < Threshold,
Default Value

Bytes Address
Each LSB of VHIGHh represents 25.6mV. This register is to be used in conjunction with VHIGHl to yield a sixteen-bit value.
The value in this register is uncalibrated. The threshold value (VHIGHh;VHIGHl) is compared. bit to bit. to the value of the
voltage reading (VINh;VINl). Warning bit Wx is set if Reading > Threshold.

Each LSB of VLOWh represents 25.6mV. This register is to be used in conjunction with VLOWl to yield a sixteen-bit value. The
value in this register is uncalibrated. The threshold value (VLOWh;VLOWl) is compared. bit to bit, to the value of the voltage
reading (VINh;VINl). Warning bit Wx is set if Reading < Threshold.
