MKT_THRESHOLD_TEMP Register (RW)
Register Address Op. Default
MKT_THRESHOLD_TEMP 0x45 RW 0x0000
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
p
oint 8.5 notation using the formula (3).
SHL_REF_TEMP Register (RW)
Register Address Op. Default
SHL_REF_TEMP 0x46 RW 0x0000
Shelf life reference temperature expressed °C. The temperature in °C is
expressed in fixed point 8.5 notation using the formula (3).
SHL_Q10_TEMP Register (RW - 2 words)
Register Address Op. Default
SHL_Q10_TEMP_L 0x47 RW 0x0000
SHL_Q10_TEMP_H 0x48 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
po
int fields and the two registers is reported below:
Sign Exponent Mantissa
31 30…23 (8 bits) 22…16 15…0 (23 bits)
SHL_Q10_TEMP_H sig SHL_Q10_TEMP_H exp SHL_Q10_TEMP_L
SHL_THRESHOLD Register (RW)
Register Address Op. Default
SHL_THRESHOLD 0x4A RW 0x0000
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.
