Figure B-1. Three Possible Mapping Options
When programming Flash memory on the MVME177, the
destination starting address argument to the PFLASH command
may be specified in two ways:
A relative offset into the Flash memory array.
Ð $0 = the bottom or lowest possible Flash memory array
location.
Ð $3FFFFF = the top location or end of the Flash memory
array.
An equivalent to the physical address that will apply when
the entire Flash is mapped in (as when J8 is removed).
Ð $FF800000 = the bottom or lowest possible Flash memory
array location.
Ð $FFBFFFFF = the top location or end of Flash memory.
