Function
measured temperature data for the local
zone*
read only
Operation
TEMP0 Power-Up Value: 0000 0000_b = 00_h (0°C)^†
TEMP0 Command Byte Value: 0000 0000_b = 00_h
* Each LSB represents one degree Centigrade. The values are
in a two's complement format such that 0°C is reported as
0000 0000_b. See "Temperature Data Format" for more details.
† _{TEMP0 will contain measured temperature data after the}
completion of one conversion.
