This register provides the threshold temperature value for the alarm of the 

Mean Kinetic algorithm. If the Mean Kinetic value is greater than the thresh-

old value the alarm bit is set. The temperature in °C is expressed in fixed 

point 8.5 notation using the formula (3).

SHL_REF_TEMP Register (RW)

SHL_REF_TEMP

Shelf life reference temperature expressed °C. The temperature in °C is 

expressed in fixed point 8.5 notation using the formula (3).

RW

0x0000

This value, represented in floating point 32bits (IEEE-754) notation, is used 

to configure the Arrhenius algorithm behaviour. It is defined as the ratio of 

the reaction rate constants at temperatures differing by 10 °C from the ref-

erence temperature. It is a unit less number. The map between the floating 

point fields and the two registers is reported below:

Shelf life threshold represents the threshold value for the alarm of the 

Arrhenius algorithm. If the SHL_TIME value becomes smaller of the Thresh-

old value the alarm bit is set. It is expressed in hours.
