• Flash Key Code Register (FKEY)
FKEY is a register for software protection that enables download of on-chip program and
programming/erasing of flash memory. Before setting the SCO bit to 1 in order to download on-
chip program or executing the downloaded programming/erasing program, these processing
cannot be executed if the key code is not written.

Description
Key Code
Only when H'A5 is written, writing to the SCO bit is valid.
When the value other than H'A5 is written to FKEY, 1
cannot be set to the SCO bit. Therefore downloading to
the on-chip RAM cannot be executed.
Only when H'5A is written, programming/erasing can be
executed. Even if the on-chip programming/erasing
program is executed, the flash memory cannot be
programmed or erased when the value other than H'5A
is written to FKEY.
H'A5: Writing to the SCO bit is enabled. (The SCO bit
H'5A: Programming/erasing is enabled. (The value other
H'00: Initial value
cannot be set by the value other than H'A5.)
than H'A5 is in software protection state.)
