7.3 Area Overview
7.3.1 Address Map
In the architecture, this LSI has a 32-bit address space, which is divided into cache-enabled,
cache-disabled, and on-chip spaces (on-chip RAM, on-chip peripheral modules, and reserved
areas) according to the upper bits of the address.
External address spaces CS0, CS3 to CS6 are cache-enabled when internal address A29 = 0 or
cache-disabled when A29 = 1.
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.
