7.5.14.1 Multiple Device Access Write

The master transmits an MDA write address followed by the pointer address of the register to be accessed; see Table 4. Following the pointer, all of the TMP103 devices on the bus acknowledge and wait for the next byte of data to be written to the addressed registers. When the data byte is received by the TMP103 devices, they store and acknowledge the transmitted byte. The TMP103 devices store the same data on all devices on the bus in one transaction; see Figure 4.
