... To enable higher data rates (or in cases where Ethernet protocol processing is not required), the Gigabit-Ethernet MACs can be configured as 8-bit and/or 16-bit packet FIFOs. The BCM1480 also integrates a 64-bit, 133-MHz PCI-X local bus for direct connection to I/O devices. Four serial ports are available for use as UARTs for console ports. ...
