Area Overview

8.3.1

Address Map

In the architecture, this LSI has a 32-bit address space, which is divided into external address

space and on-chip spaces (on-chip ROM, on-chip RAM, on-chip peripheral modules, and reserved

areas) according to the upper bits of the address.

The kind of memory to be connected and the data bus width are specified in each partial space.

The address map for the external address space is listed below.

Note:

For the on-chip RAM space, access the addresses shown in section 22, On-Chip RAM.

For the on-chip peripheral module space, access the addresses shown in section 26,

List of Registers. Do not access addresses which are not described in these sections.

Otherwise, the correct operation cannot be guaranteed.
