This chapter describes each block of the CPU hardware.
2.1 CPU
This section describes the memory space and register composing CPU
hardware.
2.1.1 Memory Space
F2MC-8L CPU has a memory space of 64 Kilobytes. All I/O, data, and
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. Fig.2.1 shows the structure of the
memory space for the MB89950 series of microcontrollers.
