There are two 32Mb memory modules on the 6534, however, you cannot use them both with the same DIO group. One module is for group one, the other for group two.
Here are the group configurations.
Group Port
1 0
1 0,1
1 0,1,2,3
2 2
2 2,3
It is possible to use both groups to output your data, this would require you to split up the data into two seperate pieces.
