SCPS141J September 2006 – March 2021 PCA9534A
PRODUCTION DATA
Data is transmitted to the PCA9534A by sending the device address and setting the least-significant bit 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.
