Host Interface (PCI): This block provides the communication path between the Host and CX28500.
Expansion Bus (EBUS): The EBUS is an extension of the Host Interface, which provides the Host with access
to control other devices on the local PC board.
Serial Interface Unit (SIU): This block provides the interface between 32 serial ports and the Receive and
Transmit Serial Line Processors block. A temporal buffering space is provided by SIU that is 48 bits per port,
