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.

Geographical address; that is, the VME slot number. See the VME64 Specification and the
VME64 Extensions for details. As a result, a 512K byte CR/CSR area can be accessed
from the VMEbus using the CR/CSR AM code.
