Section 21 Flash Memory (0.18-μm F-ZTAT Version)
21.1.3
This LSI’s flash memory is configured by the 256-kbyte/384-kbyte/512-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 the 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 if it is in ROM valid mode. However,
the user boot MAT can be programmed only in boot mode and PROM mode.
The size of the user MAT is different from that of the user boot MAT. An address which exceeds
the size of the 8-kbyte user boot MAT should not be accessed. If the attempt is made, data is read
as undefined value.
