Fig 4. PCA9535A device address  
A2, A1 and A0 are the hardware address package pins and are held to either HIGH  
(logic 1) or LOW (logic 0) to assign one of the eight possible slave addresses. The last bit  
of the slave address (R/W) defines the operation (read or write) to be performed. A HIGH  
(logic 1) selects a read operation, while a LOW (logic 0) selects a write operation.  
6.2 Registers  
6.2.1 Pointer register and command byte  
Following the successful acknowledgement of the address byte, the bus master sends a  
command byte, which is stored in the Pointer register in the PCA9535A. The lower  
three bits of this data byte state the operation (read or write) and the internal registers  
(Input, Output, Polarity Inversion, or Configuration) that will be affected. This register is  
write only.
