Flash Memory Error
Indicates an error occurs during programming and erasing
flash memory.
When FLER is set to 1, flash memory enters the error
protection state.
When FLER is set to 1, high voltage is applied to the
internal flash memory. To reduce the damage to flash
memory, the reset signal must be released after the reset
period of 100 µs which is longer than normal.
0: Flash memory operates normally
Programming/erasing protection for flash memory (error
protection) is invalid.
[Clearing condition]
At a power-on reset
1: Indicates an error occurs during programming/erasing
