3 PCI Interface

The TCP201 is accessible in the PCI Memory space.

The PCI9030 PCI Target Chip from PLX Technology is used as PCI target device for accessing the IP
interface. A FPGA is used on the PCI9030 local bus to build the IP interface and provide IP interface
control registers.

The PCI9030 provides four local spaces 0:3 that are used for the IP interface.

Basic PCI9030 register configuration is loaded from a serial EEPROM after power-up or board reset.
