Data is transmitted to the PCA9534 registers using the write mode as shown in Figures 6 and 7. Data is read from the PCA9534 registers using
the read mode as shown in Figures 8 and 9. These devices do not implement an auto-increment function so once a command byte has been
sent, the register which was addressed will continue to be accessed by reads until a new command byte has been sent.
