MX98905B
The 8 kwords of memory can be accessed directly by
the host system in the same manner as any other
memory. Typically the programmer can remove data
from this buffer using a "MOV" or "MOVSW"
instruction.
In compatible mode, data located at address 4000h-
7FFFH, 8000H-BFFFH and C000H-FFFFH is just the
mirror of contents located at 0000H-3FFFH.
