The error protection function is invalid for abnormal operations other than the FLER bit setting
conditions. Also, if a certain time has elapsed before this protection state is entered, damage may
already have been caused to the flash memory. Consequently, this function cannot provide
complete protection against damage to flash memory.
To prevent such abnormal operations, therefore, it is necessary to ensure correct operation in
accordance with the program/erase algorithm, with the flash write enable (FWE) voltage applied,
and to conduct constant monitoring for MCU errors, internally and externally, using the watchdog
timer or other means. There may also be cases where the flash memory is in an erroneous
programming or erroneous erasing state at the point of transition to this protection mode, or where
programming or erasing is not properly carried out because of an abort. In cases such as these, a
forced recovery (program rewrite) must be executed using boot mode. However, it may also
happen that boot mode cannot be normally initiated because of overprogramming or overerasing.
(When High Level Is Applied to FWE Pin in Mode 5, 6, and 7 (On-Chip ROM Enabled))
