SBOS891B October 2018 – April 2021 TMP144
The host can initiate an individual read and write command to a particular TMP144 device in the daisy-chain by sending the read/write command. The read/write command consists of these parameters:
As shown in Figure 7-14, an individual device write command is indicated by C = 0. The host must transfer at least one more byte of data for the register indicated by bits C[2:1]. The TMP144 in the daisy-chain that corresponds to the device ID noted by bits C[6:3] then updates the appropriate register.
As shown in Figure 7-15, an individual device read command is indicated by C = 1. As shown in Figure 7-16, the TMP144 in the daisy-chain that corresponds to the device ID pointed by bits C[6:3] then breaks the bus, transmits the data from the register pointed by bits C[2:1], and reconnects the bus.
