4.1.4 Local Space 3 Address Map
The PCI9030 local space 3 is used for the IP A-D Memory space (8 bit port). This space allows linear
addressing of the IP memory space for IP’s with 8 bit port width (D0-D7) only.
The PCI base address for local space 3 can be obtained from the PCIBAR5 Register at offset 0x24 in
the PCI9030 PCI configuration register space.

4.2.1 Revision ID Register
The Revision ID Register shows the revision of the on board IP FPGA logic. Initial Value is 0x00.
Changes in the on board FPGA logic will be signed by incrementing the register value.
