Description
Key Code
When H'A5 is written to FKEY, writing to the SCO bit in
FCCS is enabled. When a value other than H'A5 is
written, the SCO bit cannot be set to 1. Therefore, the
on-chip program cannot be downloaded to the on-chip
RAM.
Only when H'5A is written can programming/erasure of
the flash memory be executed. When a value other than
H'5A is written, even if the programming/erasing
program is executed, programming/erasure cannot be
performed.
H'A5: Writing to the SCO bit is enabled. (The SCO bit

cannot be set to 1 when FKEY is a value other
than H'A5.)
enabled. (When FKEY is a value other than H'A5,
the software protection state is entered.)
