Data is transmitted to the PCA9536 registers using the Write mode as shown in Figure 7
and Figure 8. Data is read from the PCA9536 registers using the Read mode as shown in
Figure 9 and Figure 10. 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.
Remark: At power-on reset, all registers return to default values.
