Chapter 1 Overview

The SFR area in each

model extends toward

lower-address locations

as much as available.

The RAM area in each

model extends toward

higher-address loca-

tions as much as

available.

1.2 Address Space

Fig. 1.2.1 shows an address space.

Addresses 0000016 through 003FF16 make up an SFR (special function register) area. In individual models

of the M16C/60, M16C/20, M16C/Tiny series, the SFR area extends from 003FF16 toward lower addresses.

Addresses from 0040016 on make up a memory area. In individual models of the M16C/60, M16C/20,

M16C/Tiny series, a RAM area extends from address 0040016 toward higher addresses, and a ROM area

extends from FFFFF16 toward lower addresses. Addresses FFE0016 through FFFFF16 make up a fixed

vector area.
