SNIS207 December 2018 LM95071-Q1
The master controller may enable the shutdown mode for the purpose of reducing power consumption or for reading the Manufacturer/Device ID information. The shutdown mode is enabled by writing XX FF hex to the LM95071-Q1 as shown in Figure 13c. The serial bus is still active when the LM95071-Q1 is in shutdown. When in shutdown mode the LM95071-Q1 always will output 1000 0000 0000 1111. This is the Manufacturer/Device ID information. The first 5-bits of the field (1000 0XXX) are reserved for the manufacturer ID.
