Hi again,

Just checked it out.
According to the datasheet from Motorola, the 56001 only has 16 address lines (A0-A15).
This gives an addressable range of 32kword..

This can be expanded by using bankswitching; by decoding a specified address and using it to switch the upper memoryhalf, the addressable memoryrange could be extended. There is not much point in this however, as the DSP has no PMMU to sort out the addressing.
