Outbound window 3 (OTAT3) is enabled, 2eSST timing at SST320, transfer mode of SCT,
A16/D32 Supervisory access. The window accepts transfers on the PCI-X Local Bus from
0xB3FF0000-0xB3FF0000 and translates them onto the VMEbus using an offset of
0x4C000000, thus an access to 0xB3FF0000 on the PCI-X Local Bus becomes an access
to 0xFFFF0000 on the VMEbus.

Firmware Settings
The following sections provide additional information pertaining to the VME firmware settings
of the MVME3100. A few VME settings are controlled by hardware jumpers while the majority
of the VME settings are managed by the firmware command utility vmeCfg.

of the VME settings are managed by the firmware command utility vmeCfg.
CR/CSR Settings
The CR/CSR base address is initialized to the appropriate setting based on the 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.
