7.6.4.1 Writes

Data is transmitted to the TCAL6408 by sending the device address and setting the least-significant bit (LSB) to a logic 0 (see Figure 7-7 for device address). The command byte is sent after the address and determines which register receives the data that follows the command byte. There is no limitation on the number of data bytes sent in one write transmission.
