DEVICE ADDRESS
Following a START condition the bus master must output the
address of the slave it is accessing. The address of the PCA9560 is
shown in Figure 3. To conserve power, no internal pull-up resistors
are incorporated on the hardware selectable address pins and they
must be pulled HIGH or LOW.
The last bit of the slave address byte defines the operation to be
performed. When set to logic 1 a read is selected while a logic 0
selects a write operation.
CONTROL REGISTER DEFINITION
Following the address and acknowledge bit with logic 0 in the read/write bit, the first byte written is the command byte. If the command byte is
reserved and therefore not valid, it will not be acknowledged. Only valid command bytes will be acknowledged.

CONTROL REGISTER
Following the successful acknowledgement of the slave address,
the bus master will send a byte to the PCA9560, which will be stored
in the control register. This register can be written and read via the
