5. 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.
6. The Flash and EPROM 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 PROM device is accessed. If
GPIO3 is not installed, the Flash is accessed.
7. 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.
Table 3-2 focuses on the ‘‘Local I/O Devices’’ portion of the local bus main
memory map.
