Read T
This command reads the value of the T
the next nine clock cycles clock out the 9–bit temperature limit which sets the threshold for operation of

Read Counter [A0h]
This command reads the value of the counter byte. The next nine clock cycles will output the contents of
this register.
Read Slope [A9h]
This command reads the value of the slope counter byte from the DS1720. The next nine clock cycles
will output the contents of this register.
Start Convert T [EEh]
This command begins a temperature conversion. No further data is required. In one–shot mode, the
temperature conversion will be performed and then the DS1720 will remain idle. In continuous mode, this
command will initiate continuous conversions.
Stop Convert T [22h]
This command stops temperature conversion. No further data is required. This command may be used to
halt a DS1720 in continuous conversion mode. After issuing this command, the current temperature
measurement will be completed, and then the DS1720 will remain idle until a Start Convert T is issued to
resume continuous operation.
Write Config [0Ch]
This command writes to the configuration register. After issuing this command, the next eight clock
cycles clock in the value of the configuration register.
Read Config [ACh
This command reads the value in the configuration register. After issuing this command, the next eight
clock cycles output the value of the configuration register.
