7.3.7 Individual Read and Write

The host can initiate an individual read/write command to a particular TMP104 in the daisy-chain by sending the read/write command. The read/write command consists of these parameters:

  • P7 = 0
  • P6-P3 = the device ID
  • P2-P1 = the data register pointer; see Table 4
  • P0 = indicates read/write control

P0 = 0 indicates an individual write command; the host must transfer one more byte of data for the register indicated by bits P2-P1. The TMP104 in the daisy-chain that corresponds to the device ID noted by bits P6-P3 then updates the appropriate register. P0 = 1 indicates an individual read command; as shown in Figure 12, the TMP104 in the daisy-chain that corresponds to the device ID pointed by bits P6-P3 then breaks the bus, transmits the data from the register pointed by bits P2-P1, and reconnects the bus.
