Stop Convert T [22h]
This command stops temperature conversion. No further data is required. This command may be used to
halt a DS1721 in continuous conversion mode. After issuing this command, the current temperature
measurement will be completed, stored and the DS1721 will remain idle until a Start Convert T is issued
to resume conversions.

NOTES:
1.
Data direction depends upon R/
W
bit in the 2-wire control byte.
2.
In continuous conversion mode, a Stop Convert T command will halt continuous conversion. To
restart, the Start Convert T command must be issued. In one-shot mode, a Start Convert T command
must be issued for every temperature reading desired.
3.
If the user only desires 8-bit thermometer readings, the master need only read 1 data byte and follow
with a NACK and STOP. If higher resolution is required, 2 bytes must be read.
