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.
