7.4.4.1 Writes
Data is transmitted to the PCA9538 by sending the device address and setting the least-significant bit (LSB) to a logic 0 (see Figure 7-6 for device address). The command byte is sent after the address and determines which register receives the data that follows the command byte (see Figure 7-8 and Figure 7-9). There is no limitation on the number of data bytes sent in one write transmission.
