Description
Unused
Returns 0.
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
17.9.3, Error Protection.
0: Normal operation (FLER = 0)
1: Error protection state, and programming cannot be
performed (FLER = 1)
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
