Address Space

This LSI has a 4-Gbyte address space, consisting of the range of addresses from 0000 0000h to FFFF FFFFh. That is,

linear access to an address space of up to 4 Gbytes is possible, and this contains both program and data areas.

Figure 3.1 shows the memory maps.

Notes: 1. The layout of the address space in boot mode is the same as in single-chip mode.

2. Reserved areas should not be accessed, since the correct operation of LSI is not guaranteed

if they are accessed.

3. For details on the FCU, see section 30, ROM (Flash Memory for Code Storage) and section 31, Data

Flash (Flash Memory for Data Storage) in the User’s manual: Hardware.
