3.1 Outline of the Address Space

The logical addresses of the M32R are always handled in 32 bits, providing a linear address space of up to 4

Gbytes. The address space of the M32R/ECU consists of the following:

(1) User space

• Internal ROM area

• External extension area

• Internal RAM area

• SFR (Special Function Register) area

The 2 Gbytes from the address H’0000 0000 to the address H’7FFF FFFF comprise the user space.

Located in this space are the internal ROM area, an external extension area, the internal RAM area and

the SFR (Special Function Register) area (in which a set of internal peripheral I/O registers exist). Of

these, the internal ROM and external extension areas are located differently depending on mode set-

tings as will be described later.

(2) System space (This area is closed to the user)

The 2 Gbytes from the address H’8000 0000 to the address H’FFFF FFFF comprise the system space.

This space (except for SFR area for NBD control) is reserved for use by development tools such as an in-

circuit emulator and debug monitor.
