FVACR modifies the space from which the vector table data of the NMI interrupts is read.
Normally the vector table data is read from the address spaces from H'00001C to H'00001F.

Description
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.
Erasing of the user boot MAT should be performed in
boot mode or PROM mode.
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)
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
Unused
Return 0.
Success/Fail
Indicates whether the erasing processing is ended
normally or not.
0: Erasure is ended normally (no error)
1: Erasure is ended abnormally (error occurs)
0: Erasure has ended normally
1: Erasure has ended abnormally (erasure result is not
