VME Settings
As shipped from the factory, the firmware on the MVME5500 will
program default values into the Universe II VME Interface chip. The
firmware allows certain VME settings to be changed in order for the user
to customize his/her environment. The following is a description of the
default VME settings that are changeable by the user. For more
information, refer to the MOTLoad User’s Manual and Tundra’s Universe
II User Manual, listed in
Appendix D, Related Documentation
❏
VME3PCI Master Enable = Y
N = Do not set up or enable the VMEbus Interface.
Y= Set up and enable the VMEbus Interface.
❏
PCI Slave Image 0
This image is set to zeroes and thus disabled.
❏
PCI Slave Image 1 Control = C0820000
Sets LSI1_CTL to indicate that this image is enabled, write
posting is enabled, VMEbus data width is 32 bits, VMEbus
address space is A32, data and non-supervisory AM encoding, no
BLT transfers to the VMEbus, and to accept addresses in PCI
memory space.
❏
PCI Slave Image 1 Base Address Register = 91000000
Sets LSI1_BS to indicate that the lower bound of PCI memory
addresses to be transferred to the VMEbus by this image is
0x91000000.
❏
PCI Slave Image 1 Bound Address Register = B0000000
Sets LSI1_BD to indicate that the upper bound of PCI memory
addresses to be transferred by this image is 0xB0000000.
❏
PCI Slave Image 1 Translation Offset = 70000000
Sets LSI1_TO to indicate that the PCI memory address is to be
translated by 0x70000000 before presentation on the VMEbus; the
result of the translation is: 0x91 0x70000000 =
0x101000000, thus 0x01000000 on the VMEbus.
