Memory Space
The MB89940 Series has a memory space of 64 Kbytes. All peripheral registers, RAM and ROM areas are
mapped onto the 0000H to FFFFH range. The peripheral registers address below 007FH and the RAM addresses
the range 0080H to 027FH (0080H to 047FH for MB89PV940). A part of this RAM area is also assigned as the
general-purpose registers. The ROM addresses above E000H for MB89943, or C000H for MB89945. The One-
Time PROM addresses the range above C000H. The external ROM for the piggy sample addresses the range
above 8000H. The reset vector, interrupt vectors and vectors for vector-call instructions are stored in the highest
addresses of the memory space.
