2.1CPU Memory Space

All of the data, program, and I/O areas managed by the F2MC-8FX CPU are assigned to the 64 Kbyte memory space of the F2MC-8FX CPU. The CPU can access each resource by indicating its address on the 16-bit address bus.

■CPU Memory Space

Figure 2.1-1shows the address configuration of the F2MC-8FX memory space.

The I/O area is located close to the least significant address, and the data area is arranged right above it. The data area can be divided into the register bank, stack and direct areas for each application. In contrast to the I/O area, the program area is located close to the most significant address. The reset, interrupt reset vector and vector call instruction tables are arranged in the highest part.
