Note Because the FUS LED monitors the status of several voltages on
the MVME2603/2604, it does not directly indicate the condition
of any single fuse. If the LED flickers or goes out, check all the
fuses (polyswitches).

There are three points of view for memory maps:
❏ The mapping of all resources as viewed by the processor (MPU bus
memory map)
❏ The mapping of onboard resources as viewed by PCI local bus
masters (PCI bus memory map)
❏ The mapping of onboard resources as viewed by VMEbus masters
(VMEbus memory map)
The following sections give a general description of the MVME2603/2604
memory organization from the above three points of view. Detailed
memory maps can be found in the MVME2600 Series Single Board
Computer Programmer’s Reference Guide, listed in Appendix D, Related
Documentation.
Processor Memory Map
The processor memory map configuration is under the control of the
Raven bridge controller ASIC and the Falcon memory controller chip set.
The Raven and Falcon devices adjust system mapping to suit a given
application via programmable map decoder registers. At system power-up
or reset, a default processor memory map takes over.Default Processor Memory Map
The default processor memory map that is valid at power-up or reset
remains in effect until reprogrammed for specific applications. Table 2-1
defines the entire default map ($00000000 to $FFFFFFFF). Table 2-2
further defines the map for the local I/O devices (accessible through the
PCI/ISA I/O Space).Notes
1. Default map for PCI/ISA I/O space. Allows software to determine
whether the system is MPC105-based or Falcon/Raven-based by
examining either the PHB Device ID or the CPU Type register.
2. The first 1MB of ROM/Flash bank A (soldered 4MB or 8MB
ROM/Flash) appears in this range after a reset if the rom_b_rv
control bit in the Falcon’s ROM B Base/Size register is cleared. If
the rom_b_rv control bit is set, this address range maps to
ROM/Flash bank B (socketed 1MB ROM/Flash).
