Outbound window 7 (OTAT7) is enabled, 2eSST timing at SST320, transfer mode of SCT,
CR/CSR Supervisory access. The window accepts transfers on the PCI-X Local Bus from
0xB1000000-0xB1FF0000 and translates them onto the VMEbus using an offset of
0x4F000000, thus an access to 0xB1000000 on the PCI-X Local Bus becomes an access to
0x00000000 on the VMEbus.

CR/CSR AM code.
