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

SHDN
Shutdown bit
0 = normal operation, 1 =
shutdown
D[5:0]
Reserved
Always write as zero;
reads undefined
Power-up default value: x0xx xxxxb (Not in shutdown mode)
Command byte:
0000 0011b = 03h
* 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 conver-
sion sequence once the write operation is complete.
