Flash Memory MAT Configuration
This LSI's flash memory is configured by the 96-kbyte user MAT and 8-kbyte user boot MAT.
The start address is allocated to the same address in the user MAT and user boot MAT. Therefore,
when program execution or data access is performed between two MATs, the MAT must be
switched by using FMATS.
The user MAT or user boot MAT can be read in all modes. However, the user boot MAT can be
programmed only in boot mode and programmer mode.
Address H'000000
Address H'017FFF
The size of the user MAT is different from that of the user boot MAT. An address that exceeds the
size of the 8-kbyte user boot MAT should not be accessed. If the attempt is made, data is read as
an undefined value.
