3.1

Configuration

The PCI2250 supports four secondary bus masters. Due to board space, only
three masters are supported with the EVM2250B board. The three supported
masters can be plugged into three edge connectors labeled P1, P2, and P3.
These edge connectors are configured based on the Table 3–1.

The interrupts for each connector on the secondary bus are routed according
to the 

PCI Local Bus Specification Revision 2.2, section 2.2.6. Table 3–2

depicts how the interrupts are routed on the EVM2250B evaluation board.
