#126251 - internal external and the bits...
Responding to: ???'s previous message
Toto Lotto said:
Why using XRS bits to describe the amount of internal xram ?

For backward compatibility (with Intel's RD (256B) and Philips' RD2 (768B).
Also for having the option to (dynamically) map true external RAM at the same memory space.

Is there a possibilty to share the same memory space between internal and external xram?


Yes.
