Shutdown

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 Texas Instruments

production testing only. See Serial Bus Interface for a complete discussion.
