I just noticed something. 48KB of linear ROM space would require a minimum of
16 address lines. As far as I can see, the DOC2000 only has 13 address lines
(ie. 8KB address space). I'm a bit confused here.
How does the DOC distinguish between accesses to the linear ROM and accesses to
the NAND-Flash ?
