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.
