• Switching of the MATs by FMATS should be required when programming/erasing of the user
MAT is operated in user boot mode. The program that switches the MATs should be executed
from the on-chip RAM. (For details, see section 24.10, Switching between User MAT and
User Boot MAT.) Make sure you know which MAT is currently selected when switching
them.
• When the program data storage area is within the flash memory area, an error will occur even
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.
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 24.9 to 24.13.
