MKT_VAL register (RO)
Register Address Op. Default
MKT_VAL 0x52 RO 0x0000
MKT_VAL register represents the current value of the Mean Kinetic Temperature. It is expressed in °C using a fixed
point 8.5 notation, see formula (3). Default value is 0. MKT_VAL register is set to 0 after a reset operation.
SHL_TIME register (RO – 2 words)
Register Address Op. Default
SHL_TIME_L 0x53 RO 0x0000
SHL_TIME_H 0x54 RO 0x0000
This register, represented in floating point 32bits (IEEE-754) notation, provides to the user the current value of the
remaining shelf life expressed in hours. Default value is 0. SHL_TIME register is set to 0 after a reset operation.
The map between the floating point fields and the two registers is reported below:
Sign Exponent Mantissa
31 30..23 22..16 15..0
SHL_TIME_H SHL_TIME_L
BIN_ALARM register (RO)
Register Address Op. Default
BIN_ALARM 0x55 RO 0x0000
The register is composed by the following fields:
15 … 2 1 0
BIN15_EN … BIN02_EN BIN01_EN BIN00_EN
0 0 0 0 0 Default
BINX_EN bit (X = 0..15) is set to 1 if the value of the BIN_COUNTER_X register is greater than the corresponding
BIN_THRESHOLD_X register value. BIN_ALRM register is set to 0 after a reset operation.
BIN_COUNTER registers (RO - 16 words)
Register Address Op. Default
BIN_COUNTER_0 0x56 RO 0x0000
BIN_COUNTER_1 0x57 RO 0x0000
... ... .. 0x0000
BIN_COUNTER_15 0x65 RO 0x0000
These registers represent the number of temperature samples in the range of the corresponding bin. Default value is 0
for each counter. All the BIN_COUNTER registers are set to 0 after a reset operation.
LAST_SAMPLE_VALUE register (RO)
Register Address Op. Default
LAST_SAMPLE_VALUE 0x66 RO 0x0000
It represents the last temperature value read from the sensor (even if not stored in the log memory).
LAST_SAMPLE_VALUE register is set to 0 after a reset operation.
