Outbound Image 3 Ending Address Upper Register = 00000000

Outbound Image 3 Ending Address Lower Register = B3FF0000

Outbound Image 3 Translation Offset Upper Register = 00000000

Outbound Image 3 Translation Offset Lower Register = 4C000000

Outbound Image 3 2eSST Broadcast Select Register = 00000000

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.

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.

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.

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.
