Description
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
[Clearing condition]
At a power-on reset
1: Indicates an error occurs during
[Setting condition]
See section 17.6.3, Error Protection.
