Hi all,

I am working on ADSP-21489 with 16-bit external flash memory thru AMI bank 1. According to the ADSP-214xx SHARC processor hardware manual (page 3-11), bank 1 can accommodate up to 8M words. I am trying to find out if there is any way to access more than 8M flash memory. In Table 3-3 last row it shows 24 external physical address lines can be used, but only in 16-bit data packing mode. I have to access 16M by 16-bit data reside on external flash. I wonder if anyone has dealed with this issue?

Thanks in advance.
