Note 1

: To allow the selection of the configuration address to a user defined location, these Configuration Address

Bytes are used. There is no restriction on the address chosen, except that A0 is 0, that is, the address must be on an

even byte boundary. As soon as both bytes are changed, the configuration space is moved to the specified location with

no delay (Write byte 0, then byte 1; writing CR27 changes the base address).

The configuration address is only reset to its default address upon a PCI Reset or Vcc POR.

Note

: The default configuration address is either 02Eh or 04Eh, as specified by the SYSOPT pin.
