Memory Space
The MB89940 Series has a memory space of 64 Kbytes. All peripheral registers, RAM and ROM areas are
mapped onto the 0000
H
to FFFF
H
range. The peripheral registers address below 007F
H
and the RAM addresses
the range 0080
H
to 027F
H
(0080
H
to 047F
H
for MB89PV940). A part of this RAM area is also assigned as the
general-purpose registers. The ROM addresses above E000
H
for MB89943, or C000
H
for MB89945. The One-
Time PROM addresses the range above C000
H
. The external ROM for the piggy sample addresses the range
above 8000
H
. The reset vector, interrupt vectors and vectors for vector-call instructions are stored in the highest
addresses of the memory space.
