Note: There is only read access to this register. Note that when both the internal temperature and humidity logging are enabled, the
two log readings are counted as one event in the Mission Samples Counter and Device Samples Counter.
Mission Start Delay
The content of the Mission Start Delay Counter register
tells how many minutes must expire from the time a mis-
sion was started until the first measurement of the mis-
sion takes place (SUTA = 0) or until the device starts
testing the temperature for a temperature alarm (SUTA =
1). The Mission Start Delay register is stored as an
unsigned 24-bit integer number. The maximum delay is
16,777,215min, equivalent to 11,650 days or roughly
31yr. If the start delay is nonzero and the SUTA bit is set
to 1, first the delay must expire before the device starts
testing for temperature alarms to begin logging data.
For a typical mission, the Mission Start Delay is 0. If a
mission is too long for a single DS1923 to store all read-
ings at the selected sample rate, one can use several
devices and set the Mission Start Delay for the second
device to start recording as soon as the memory of the
first device is full, and so on. The RO bit in the Mission
Control register (address 0213h) must be set to 0 to
prevent overwriting of collected data once the data-log
memory is full.
Maxim Integrated
Mission Timestamp
The Mission Timestamp register indicates the date and time
of the first temperature and humidity sample of the mission.
There is only read access to the Mission Timestamp register.
Mission Progress Indicator
Depending on settings in the Mission Control register
(address 0213h), the DS1923 logs temperature and/or
humidity in 8-bit or 16-bit format. The description of the
ETL and EHL bit explains where the device stores data
in its data-log memory. The Mission Samples Counter
register together with the starting address and the log-
ging format (8 or 16 bits) provide the information to iden-
tify valid blocks of data that have been gathered during
the current (MIP = 1) or latest mission (MIP = 0). See the
Data-Log Memory Usage section for an illustration. Note
that when SUTA = 1, the Mission Samples Counter does
not increment when the first sample is logged.
The number read from the Mission Samples Counter indi-
cates how often the DS1923 woke up during a mission to
measure temperature and/or humidity. The number for-
mat is 24-bit unsigned integer. The Mission Samples
Counter is reset through the Clear Memory command.
