1.0 Functional Description (Continued)
1.3 TEMPERATURE DATA FORMAT
Temperature data is represented by a 14-bit, two’s comple-
ment word with an LSB (Least Significant Bit) equal to
0.03125˚C:

The first data byte is the most significant byte with most
significant bit first, permitting only as much data as neces-
sary to be read to determine temperature condition. For
instance, if the first four bits of the temperature data indicate
an overtemperature condition, the host processor could im-
mediately take action to remedy the excessive tempera-
tures.
1.4 SHUTDOWN MODE/MANUFACTURER’S ID
Shutdown mode is enabled by writing XX FF to the LM71 as
shown in Figure 7c. The serial bus is still active when the
LM71 is in shutdown. When in shutdown mode the LM71
always will output 1000 0000 0000 1111. This is the
manufacturer’s/Device ID information. The first 5-bits of the
field (1000 0XXX) are reserved for manufacturer’s ID.
1.5 INTERNAL REGISTER STRUCTURE
The LM71 has three registers, the temperature register, the
configuration register and the manufacturer’s/device identifi-
cation register. The temperature and manufacturer’s/device
identification registers are read only. The configuration reg-
ister is write only.

Shutdown
D0–D15 set to XX FF hex enables shutdown mode.
D0–D15 set to 00 00 hex sets Continuous conversion mode.
Note: setting D0-D15 to any other values may place the LM70 into a manufacturer’s test mode, upon which the LM71 will stop
responding as described. These test modes are to be used for National Semiconductor production testing only. See Section 1.2
Serial Bus Interface for a complete discussion.
