Processor PREP Memory Map
The Raven/Falcon chipset can be programmed for PREP-compatible
memory map. The following table shows the PREP memory map of the
MVME2600/2700 series from the point of view of the processor.
Notes:
1. Programmable via Falcon chipset.
2. Programmable via Raven ASIC.
3. The actual size of each ROM/FLASH bank may vary.
4. The first 1 Mbyte of ROM/FLASH Bank A appears at this range
after a reset if the rom_b_rv control bit is cleared. If the rom_b_rv
