22.9.2
The software protection protects the flash memory against programming/erasure by disabling
download of the programming/erasing program, using the key code, and by the RAMER setting.
Table 22.13 Software Protection
22.9.3
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/erasure 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/erasure 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/erasure.
• When the flash memory is read from during programming/erasure (including a vector read or
• When a SLEEP instruction is executed (including software-standby mode) during

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/erasure are disabled unless the
required key code is written in FKEY.
The programming/erasing protection state is
entered when the RAMS bit in the RAM emulation
register (RAMER) is set to 1.
