Erasure Mode Related Setting Error Detect

Detects the error protection state and returns the result.

When the error protection state is entered, this bit is set

to 1. Whether the error protection state is entered or not

can be confirmed with the FLER bit in FCCS. For

conditions to enter the error protection state, see section

25.9.3, Error Protection.

0: Normal operation (FLER = 0)

1: Error protection state, and programming cannot be

performed (FLER = 1)



R/W

Erasure Execution Error Detect

Returns 1 when the user MAT could not be erased or

when the flash memory related register settings are

partially changed. If this bit is set to 1, there is a high

possibility that the user MAT has been erased partially.

In this case, after removing the error factor, erase the

user MAT. If FMATS is set to H'AA and the user boot

MAT is selected, an error occurs when erasure is

performed. In this case, both the user MAT and user

boot MAT have not been erased. Erasing of the user

boot MAT should be performed in boot mode or

programmer mode.

0: Erasure has ended normally

1: Erasure has ended abnormally
