I was working on a 5502 project in early 2007... I recall that you have to
divide the
EMIF memory map values shown in the data sheet by 2 for 32-bit addressing.
A2 should be connected to A0 on your EMIF device (SRAM, Flash, SDRAM devices).
For
16-bit or 32-bit wide SRAM or SDRAM devices, the byte-enable signals need to
be
connected.
