Technical Data
246
The general-purpose chip selects can be programmed to drive other
chip-select signals as well as their own memory areas. Although all of
the eight possible combinations of the bits G1DG2, G1DPC, and G2DPC
are allowed, some combinations cause operations which do not
perform as one might expect. The results of all combinations are defined
in
The table assumes that none of the chip-select ranges overlap.
