The PCI Bridge Adapter FPGA provides two read/write registers which are used for access
enabling and memory mapping as follows.
Table 4-3: PCI Configuration Register Write Values
Register size
16 bits Bit 1 only; other bits are zero.
32 bits Bits 31 to 22; other bits are zero.
All utility software for the S5U13506B00C evaluation board is fully PCI compliant and
handles the PCI configuration registers automatically.
