MC-8L CPU has 64 Kbytes of memory. All I/O, data program areas are located in this space. The I/O area is
near the lowest address and the data area is immediately above it. The data area can be divided into register,
stack, and direct-address areas according to the applications. The program area is located near the highest
address, and the tables of interrupt and reset vectors and vector-call instructions are at the highest address in
this area. The following figure shows the structure of the memory space for the MB89950 series of
microcontrollers.
