MVME162-453
The EPROM and Flash are sized by the MCchip ASIC from an
8-bit private bus to the 32-bit MPU local bus. Because the
device size is less than the allocated memory map for some
entries, the device contents repeat for those entries.
If jumper GPIO3 is installed, the Flash device is accessed. If
GPIO3 is not installed, the EPROM is accessed.

These areas are not decoded unless one of the programmable
decoders are initialized to decode this space. If they are not
decoded, an access to this address range will generate a local
bus timeout. The local bus timer must be enabled.

Description
MVME162-453
Memory Maps
There are two points of view for memory maps:
❏ The mapping of all resources as viewed by local bus masters (local bus
memory map)
❏ The mapping of onboard resources as viewed by VMEbus masters
(VMEbus memory map)
Local Bus Memory Map
The local bus memory map is split into different address spaces by the
Transfer Type (TT) signals. The local resources respond to the normal access
and interrupt acknowledge codes.
Normal Address Range
The memory map of devices that respond to the normal address range is
shown in the following tables. The normal address range is defined by the TT
signals on the local bus. For the MVME162, transfer types 0, 1, and 2 define the
normal address range. Table 3-1 defines the entire map ($00000000 to
$FFFFFFFF). Many areas of the map are user-programmable, and suggested
uses are shown in the table. The cache inhibit function is programmable in the
MC68xx040 MMU. The onboard I/O space must be marked ‘‘cache inhibit’’
and serialized in its page table. Table 3-2 further defines the map for the local
I/O devices
