R/W Description
5
EE
Undefined R/W
Erasure Execution Error Detect
1 is returned to this bit when the user MAT could not be
erased or when flash-memory related register settings
are partially changed on returning from the user branch
processing.
If this bit is set to 1, there is a high possibility that the
user MAT is partially erased. 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 are
not erased.
Erasure of the user boot MAT must be executed in boot
mode or programmer mode.
0: Erasure has ended normally
1: Erasure has ended abnormally (erasure result is not
guaranteed)
4
FK
Undefined R/W
Flash Key Register Error Detect
Returns the check result of FKEY value before start of
the erasing processing.
0: FKEY setting is normal (FKEY = H'5A)
1: FKEY setting is error (FKEY = value other than H'5A)
3
EB
Undefined R/W
Erase Block Select Error Detect
Returns the check result whether the specified erase-
block number is in the block range of the user MAT.
0: Setting of erase-block number is normal
1: Setting of erase-block number is abnormal
2, 1 ⎯
Undefined R/W
Unused
Return 0.
0
SF
Undefined R/W
Success/Fail
Indicates whether the erasing processing has ended
normally or not.
0: Erasure has ended normally (no error)
1: Erasure has ended abnormally (error occurs)
