25.1 Features
Description amended
This LSI has 1.5-Mbyte on-chip flash memory. The flash
memory has the following features.
• Two flash-memory MATs according to LSI initiation
mode
⎯ The user MAT is initiated at a power-on reset in
user mode: 1 Mbyte
⎯ The user boot MAT is initiated at a power-on reset
in user boot mode: 8 kbytes
• Two flash-memory MATs according to LSI initiation
mode
⎯ The user MAT is initiated at a power-on reset in
user mode: 1.5 Mbyte
⎯ The user boot MAT is initiated at a power-on reset
in user boot mode: 12 Kbytes
• Operating frequency at programming/erasing
The operating frequency at programming/erasing is a
maximum of 40 MHz.

This LSI's flash memory is configured by the 1-Mbyte user
MAT and 8-kbyte user boot MAT
The user MAT is divided into two 512-kbyte banks (bank 0
and bank 1).

Description amended
This LSI's flash memory is configured by the 1.5-Mbyte
user MAT and 12-Kbyte user boot MAT
The user MAT is divided into three 512-Kbyte banks (bank
0, bank 1 and bank 2).

Address H'00,0000-H'00,2FFF 12 Kbytes
The user MAT and user boot MAT have different memory
sizes. Do not access a user boot MAT that is 8 kbytes or
more. When a user boot MAT exceeding 8 kbytes is read
from, an undefined value is read.

The user MAT is divided into 128 kbytes (seven blocks), 96
kbytes (one block), and 4 kbytes (eight blocks) as shown in
figure 23.4.

Description amended
The user MAT and user boot MAT have different memory
sizes. Do not access a user boot MAT that is 12 Kbytes or
more. When a user boot MAT exceeding 12 Kbytes is read
from, an undefined value is read.
