1.0 Functional Description
1.5 INTERNAL REGISTER STRUCTURE
The LM95071 has three registers: the temperature register,
the configuration register and the Manufacturer/Device iden-
tification register. The temperature and Manufacturer/Device
identification registers are read only. The configuration reg-
ister is write only.
1.5.1 Configuration Register
(Selects shutdown or continuous conversion modes):
D0–D15 set to XX FF hex enables shutdown mode.
D0–D15 set to XX 00 hex sets continuous-conversion mode.
Note: setting D0-D15 to any other values may place the LM95071 into a manufacturer’s test mode, upon which the LM95071 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.
1.5.2 Temperature Register
D0–D1: Logic 1 will be output on SI/0.
D2–D15: Temperature Data. One LSB = 0.03125˚C. Two’s complement format.
1.5.3 Manufacturer/Device ID Register
D0–D1: Logic 1 will be output on SI/0.
D2–D15: Manufacturer/Device ID Data. This register is accessed whenever the LM95071 is in shutdown mode.
