Operation
D[7:0]
Measured temperature data for the remote zone.
Read only
Power-up default value: 0000 0000
b
= 00
h
= (0癈)
(11)
Read command byte: 0000 0001
b
= 01
h
Each LSB represents one degree centigrade. The values are in a twos complement binary format such that 0癈 is
reported as 0000 0000b. See the Temperature Data Format section for more details.
Note:
11. TEMP will contain measured temperature data after the completion of one conversion.

D7
Reserved
Always writes as zero; reads undefined
D6
Shutdown bit
0 = normal operation; 1 = shutdown
D[5:0]
Reserved
Always writes as zero; reads undefined
Note:
12. Any write to CONFIG will result in any A/D conversion in progress being aborted and the result discarded. The A/D will begin a new conversion
sequence once the write operation is complete.
