TEMPERATURE CONVERSION COMMANDS
Read Temperature
Read Counter
Read Slope
Reads last converted temperature
value from temperature register.
Reads value of count remaining
from counter.
Reads value of the slope
accumulator.
AAh <read data>
A0h <read data>
A9h <read data>
Start Convert T
Initiates temperature conversion. EEh
Idle
1
Stop Convert T
Halts temperature conversion.
22h

THERMOSTAT COMMANDS
Write TH
Writes high temperature limit value
01h <write data>
2
into TH register.
Write TL
Writes low temperature limit value
02h <write data>
2
into TL register.
Read TH
Reads stored value of high
A1h <read data>
2
temperature limit from TH register.
Read TL
Reads stored value of low
A2h <read data>
2
temperature limit from TL register.
Write Config
Writes configuration data to
0Ch <write data>
2
configuration register.
Read Config
Reads configuration data from
ACh <read data>
2
configuration register.
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 up to 10 ms at room temperature. After issuing a write command no further
writes should be requested for at least 10 ms.
