The next generation (revision 1) of the DFL EMIF feature device requires support for more than 4 memory banks. It does not support the selective clearing of memory banks. A capability register replaces the previous control register, and contains a bitmask to indicate the presence of each memory bank. This bitmask aligns with the previous control register bitmask that served the same purpose. The control and capability registers are treated like a C Union structure in order to support both the new and old revisions of the EMIF device.
