24.9.2
The software protection protects the flash memory against programming/erasing by disabling
download of the programming/erasing program and using the key code.
Table 24.15 Software Protection
24.9.3
Error protection is a mechanism for aborting programming or erasure when a CPU runaway
occurs or operations not according to the programming/erasing procedures are detected during
programming/erasing of the flash memory. Aborting programming or erasure in such cases
prevents damage to the flash memory due to excessive programming or erasing.
If an error occurs during programming/erasing of the flash memory, the FLER bit in FCCS is set
to 1 and the error protection state is entered.
• When an interrupt request, such as NMI, occurs during programming/erasing.
• When the flash memory is read from during programming/erasing (including a vector read or

Error Protection
Description
The programming/erasing protection state is
entered when the SCO bit in FCCS is cleared to 0
to disable download of the programming/erasing
programs.
The programming/erasing protection state is
entered because download and
programming/erasing are disabled unless the
required key code is written in FKEY.
