TEMPERATURE CONVERSION COMMANDS
Read Temperature   Read last converted temperature
value from temperature register.
AAh
<read 2 bytes data>
 
Read Counter
Reads value of Count_Remain
A8h
<read data>
 
Read Slope
Reads value of the
Count_Per_C
A9h
<read data>
 
Start Convert T
Initiates temperature
conversion.
EEh
idle
1
Stop Convert T
Halts temperature conversion.
22h
idle
1
THERMOSTAT COMMANDS
Access TH
Reads or writes high
temperature limit value into TH
register.
A1h
<write data>
2
Access TL
Reads or writes low
temperature limit value into TL
register.
A2h
<write data>
2
Access Config
Reads or writes configuration
data to configuration register.
ACh
<write data>
2
 
NOTES:
1.   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.
 
2.   Writing to the E
2
 requires a maximum of 10ms at room temperature. After issuing a write command, 
no further writes should be requested for at least 10ms.
