Transitions to the reset state, and hardware standby mode are prohibited during
programming/erasing. When the reset signal is accidentally input to the chip, a longer period in
the reset state than usual (100 µs) is needed before the reset signal is released.
7. Switching of the MATs by FMATS should be needed when programming/erasing of the user
MAT is operated in user boot mode. The program which switches the MATs should be
executed in the on-chip RAM. See section 20.6, Switching between User MAT and User Boot
MAT. Please make sure you know which MAT is selected when switching between them.
8. When the data storable area indicated by programming parameter FMPDR is within the flash
memory area, an error will occur even when the data stored is normal. Therefore, the data
should be transferred to the on-chip RAM to place the address indicated by FMPDR in an area
other than the flash memory.
In consideration of these conditions, there are three sources; operating mode, the bank structure of
the user MAT, and operations.
The areas in which the programming data can be stored for execution are shown in tables.
