Refer to
The address of the PCA6416A is shown in
ADDR is the hardware address package pin and is held to either HIGH (logic 1) or LOW
(logic 0) to assign one of the two 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.
