DS1615 COMMANDS
All communication with the DS1615 is accomplished by
writing a command to the device followed by parameter
byte/s if required. Table 3 illustrates the commands sup-
ported by the DS1615.

Poll status of temperature extremes

Read Temperature
Instructs DS1615 to immediately read temperature and store result in
Current Temperature register when MIP = 0.
A5h
Clear Memory
This command clears the datalog, histogram, Temperature Alarm, Cur-
rent Samples, Start Time Stamp, Start Delay, and Sample Rate registers
when the Clear Enable bit (CLR) in the Control register is set.
The DS1615 commands are summarized below. Note
that if an invalid command is issued, no action is taken
by the device.

DS1615 Response: None
Note that good programming practice insists that the
Clear Memory command should be issued whenever
the DS1615 is programmed to begin a new datalogging
mission.

register xxxh
Where xxx represents the last register of the page that
has been accessed.
When in asynchronous mode, the TX pin becomes inac-
tive after the last register in the page and the CRC have
been transmitted. In synchronous mode, the DS1615
will continue to transmit data as long as clocks are pres-
ented to the serial interface. If clocks are presented
after the final data bit of the last register in the page, the
DS1615 will wrap–around to the first register in the page
and sequentially transmit data as long as the clocks
continue.

DS1615 Response (Host Receives): Either the
INSPEC or OUTSPEC pin will generate four low pulses.
Each pulse will be 62.5 ms in duration and will start
every half second.
This command instructs the DS1615 to generate four
low pulses on either the INSPEC or OUTSPEC LED
driver pins. The pin that is driven is dependent upon
whether any data samples fell outside of the High Tem-
