Detailed Register Descriptions
Note: Serial bus addresses shown assume that the base device address is AO
Alarm Threshold Registers
Default value for both bytes
Serial address
Byte addresses
Each LS bit of TMAXh represents one degree Celsius. TMAXl is not used, since all limit comparisons for temperature use
eight-bit values.
The eight bits of the high alarm threshold value (TMAXh) are compared to the temperature result (TEMPh). ALARM0 bit 7 is
set if Result > Threshold.

Each LS bit of TMINh represents one degree Celsius. TMINl is not used, since all limit comparisons for temperature use eight-
bit values..
The eight MS bits of the low alarm threshold value (TMINh) are compared to the temperature result (TEMPh). ALARM0 bit 6 is
set if Result < Threshold.
Default value for both bytes

Byte addresses
Each LS bit of VMAXh represents 25.6 mV and each LS bit of VMAXl represents 0.1 mV. The sixteen-bit threshold value
(VMAXh:VMAXl) is compared to the sixteen bits value of the voltage result (VINh:VINl). ALARM0 bit 5 is set if
Result > Threshold.
