STATUS Register (RO)
Register Address Op. Default
STATUS 0x51 RO ....
The STATUS Register's 16 bits are as follows:
0 - BAT_LSBIT (RO):
1 - BAT_M
SBIT (RO):
Bits 0 &1 codify the Battery Level Status
(2 bits). Value 3 means full capacity,
value 0 means minimum capacity.
The measurement is performed before each sensor acquisition. If the Battery
Level value is 1 (almost discharged) the DLR-TL001 is put automatically in
Sleep state.
2 - MEMFULL
(RO): bit to 1 to flag a full memory condition.
DLR-TL001 is put in Sleep Mode auto
matically. Default value is 0.
This bit is forced to 0 after an reset operation.
3 - ETA_ALRM (RO):
bit set to 1 when the current time exceeds the value of
the SHIPPING_DATE value plus the ETA delay register's value . Default is 0.
The bit ETA_ALLARM is forced to 0 after a reset operation.
4 - BIN_ALRM (RO): histograms Alarm bit .
the Histogram Alarm bit is set to 1 when at least one of the histogram bin
counters is greater than the corresponding threshold. Default value is 0.
BIN_ALRM bit is set to 0 after a reset operation.
5 - MKT
_ALRM (RO): set 1 when the mean Kinetics temperature is greater
than the mean Kinetic threshold temperature. Default value is 0. MKT_ALRM
bit is forced to 0 after a reset operation
6 - SHL
_ALRM (RO): the shelf life alarm bit is set to 1 when the remaining
shelf life is smaller than the shelf life threshold. Default value is 0.
SHL_ALRM bit is set to 0 after a reset operation.
7 to 15 Bits - RFU :
(Reserved for Future Use)
MKT_VAL Register (RO)
Register Address Op. Default
MKT_VAL 0x52 RO 0x0000
MKT_VAL register represents the current value of the Mean Kinetic Tempera-
ture. It is expressed in °C using a fixed point 8.5 notation, see formula (3).
Def
ault value is 0. MKT_VAL register is set to 0 after a reset operation.
