ZHCSNI7H September 2006 – March 2021 PCA9534
PRODUCTION DATA
Data is transmitted to the PCA9534 by sending the device address and setting the least significant bit (LSB) to a logic 0 (see Figure 9-6 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 9-8 and Figure 9-9). There is no limitation on the number of data bytes sent in one write transmission.
