Notes: • If the same bank area is set in two or more Virtual Flash S Bank Registers (FESBANK0-FESBANK7) and each register's flash
emulation enable bit (MODENS) is set to 1, the bank is assigned the corresponding internal RAM area in order of priority:
FESBANK0 > FESBANK1 > FESBANK2 > FESBANK3 > FESBANK4 > FESBANK5 > FESBANK6 > FESBANK7.
• If any 4-Kbyte area (S bank) specified by the Virtual Flash S Bank Register is accessed, its corresponding internal RAM area
is accessed. During virtual flash emulation mode, RAM can be accessed for read and write from both the internal RAM area and
the flash emulation areas set in the internal flash memory.
