Section 22 Flash Memory
22.2.4
Flash Memory Configuration
This LSI's flash memory is configured by the 256-Kbyte user MAT and 12-Kbyte user boot MAT.
The start address is allocated to the same address in the user MAT and user boot MAT. Therefore,
when the program execution or data access is performed between the two MATs, the MAT must
be switched by using FMATS.
The user MAT or user boot MAT can be read in all modes if it is in ROM valid mode. However,
the user boot MAT can be programmed only in boot mode and programmer mode.
<User MAT>
<User Boot MAT>

Figure 22.3 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.
