MVME3100 vmeCfg -s -o1 | Motorola instruction

Chapter 3 MOTLoad Firmware

Inbound window 0 (ITAT0) is not enabled; Virtual FIFO at 256 bytes, 2eSST timing at SST320, respond to 2eSST, 2eVME, MBLT, and BLT cycles, A32 address space, respond to Supervisor, User, Program, and Data cycles. Image maps from 0x00000000 to 0x1FFF0000 on the VMbus, translates 1x1 to the PCI-X bus (thus 1x1 to local memory). To enable this window, set bit 31 of ITAT0 to 1.

Note For Inbound Translations, the Upper Translation Offset Register needs to be set to 0xFFFFFFFF to ensure proper translations to the PCI-X Local Bus.

Outbound window 1 (OTAT1) is enabled, 2eSST timing at SST320, transfer mode of 2eSST, A32/D32 Supervisory access. The window accepts transfers on the PCI-X Local Bus from 0x91000000-0xAFFF0000 and translates them onto the VMEbus using an offset of 0x70000000, thus an access to 0x91000000 on the PCI-X Local Bus becomes an access to 0x01000000 on the VMEbus.

Outbound window 2 (OTAT2) is enabled, 2eSST timing at SST320, transfer mode of SCT, A24/D32 Supervisory access. The window accepts transfers on the PCI-X Local Bus from 0xB0000000-0xB0FF0000 and translates them onto the VMEbus using an offset of 0x40000000, thus an access to 0xB0000000 on the PCI-X Local Bus becomes an access to 0xF0000000 on the VMEbus.
