NOTES
TEMPERATURE CONVERSION COMMANDS
Read Temperature Temperature Reads last converted
temperature value from
temperature register
Read Counter Reads value of count remaining
from counter
Read Slope Reads value of the slope
accumulator
AAh <read data>
A0h <read data>
A9h <read data>
Start Convert T Initiates temperature conversion EEh Idle
Stop Convert T Halts temperature conversion 22h Idle
THERMOSTAT COMMANDS
1
1
Write T H
Writes high temperature limit
01h <write data>
2
value into T H register
Write T L
Writes low temperature limit value
02h <write data>
2
into T L register
Read T H
Reads stored value of high
A1h <read data>
2
temperature limit from T H register
Read T L
Reads stored value of low
A2h <read data>
2
temperature limit from T L register
Write Config Writes configuration data to
configuration register
Read Config Reads configuration data from
0Ch <write data>
ACh <read data>
2
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 typically requires 10 ms at room temperature. After issuing a write command, no
further writes should be requested for at least 10 ms.
