Figure 25.3 Flash Memory Configuration
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.
25.2.5 Block Division
The user MAT is divided into 256 Kbytes (four blocks), 128 Kbytes (three blocks), 96 Kbytes (one block), and 4 Kbytes
(eight blocks) as shown in figure 25.4. The user MAT can be erased in this divided-block units and the erase-block
number of EB0 to EB15 is specified when erasing.
The RAM emulation can be performed in the eight blocks of 4 Kbytes.
