Bit(s) Bit Name Read/ Description
Write
7 SIGN R/W Sign bit All registers have 2’s complement format.
The offset range for each remote is
6 32 R/W bit weight 32°C
+63.5°C/64°C. The value programmed in
5 16 R/W bit weight 16°C
this register is directly added to the actual
reading of the ADC and the modified number
4 8 R/W bit weight 8°C
is reported in the remote value registers.
3 4 R/W bit weight 4°C
2 2 R/W bit weight 2°C
1 1 R/W bit weight 1°C
0 1/2 R/W bit weight 1/2°C (0.5°C)

1-0 CR[1:0] R/W Conversion rate control bits modify the time interval for conversion of the channels enabled.
The channels enabled are converted sequentially then standby mode enabled for the
remainder of the time interval.
