21.1 Flash Memory Control

The flash memory is controlled by the flash memory control register 1 (FLSCR1), flash memory control register 2

(FLSCR2), and flash memory standby control register (FLSSTB).

Note 1: If "0xD5" is set on FLSCR2<CR1EN> with FLSCR1<FLSMD> set to "101", the flash memory goes into an active state,

and MCU consumes the same amount of current as it does during a read.

to the data area 0x8000 through 0xFFFF (standard mapping).

Assign the code area 0x8000 through 0xFFFF

to the data area 0x8000 through 0xFFFF.

11:

Assign the code area 0x1000 through 0x7FFF

to the data area 0x9000 through 0xFFFF.

Note 1:

It is prohibited to make a setting in "Reserved".

Note 2:

The flash memory control register 1 has a double-buffer structure comprised of the register FLSCR1 and a shift register.

Writing "0xD5" to the register FLSCR2 allows a register setting to be reflected and take effect in the shift register. This

means that a register setting value does not take effect until "0xD5" is written to the register FLSCR2. The value of the shift

Note 3:

FLSMD must be set to either "0y010" or "0y101".
