21.5.2
Software protection is set up by disabling the downloading of on-chip programs for programming
and erasing or by means of a key code register.

21.5.3
Error protection is a mechanism for aborting programming or erasure when an error occurs, in the
form of the microcomputer entering runaway during programming/erasing of the flash memory or
operations that are not according to the established procedures for programming/erasing. Aborting
programming or erasure in such cases prevents damage to the flash memory due to excessive
programming or erasing.
If the microcomputer malfunctions during programming/erasing of the flash memory, the FLER
bit in the FCCS register is set to 1 and the error-protection state is entered, and this aborts the
programming or erasure.

Error Protection
Description
•
•
The program/erase-protected state is
entered by clearing the SCO bit in
FCCS which disables the down-
loading of the programming/erasing
programs.
Downloading and
programming/erasing are disabled
unless the required key code is
written in FKEY. Different key codes
are used for downloading and for
programming/erasing.
