• When the program data storage area is within the flash memory area, an error will occur even
In consideration of these conditions, the areas in which the program data can be stored and
executed are determined by the combination of the processing contents, operating mode, and bank
structure of the memory MATs, as shown in tables 18.7 to 18.11.

the user MAT is operated in user boot mode. The program which switches the memory MATs
should be executed from the on-chip RAM. For details, see section 18.11, Switching between
User MAT and User Boot MAT. Make sure you know which memory MAT is currently
selected when switching them.
when the data stored is normal program data. Therefore, the data should be transferred to the
on-chip RAM to place the address that the FMPDR parameter indicates in an area other than
the flash memory.
