R/W Programming Mode Related Setting Error Detect
Returns the check result that a high level signal is input
to the FWE pin and the error protection state is not
entered. When the low level signal is input to the FWE
pin or the error protection state is entered, 1 is written to
this bit. The state can be confirmed with the FWE and
FLER bits in FCCS. For conditions to enter the error
protection state, see section 20.5.3, Error Protection.
0: FWE and FLER settings are normal (FWE = 1, FLER
= 0)
1: Programming cannot be performed (FWE = 0 or
FLER = 1)

R/W Programming Execution Error Detect
1 is returned to this bit when the specified data could not
be written because the user MAT was not erased. If this
bit is set to 1, there is a high possibility that the user MAT
is partially rewritten. 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 programming is
performed. In this case, both the user MAT and user boot
MAT are not rewritten. Programming of the user boot
MAT should be performed in boot mode or programmer
mode.
0: Programming has ended normally
1: Programming has ended abnormally (programming
result is not guaranteed)

R/W Flash Key Register Error Detect
Returns the check result of the value of FKEY before the
start of the programming processing.
0: FKEY setting is normal (FKEY = H'5A)
1: FKEY setting is error (FKEY = value other than H′5A)

R/W Write Data Address Detect
When the address in the flash memory area is specified
as the start address of the storage destination of the
program data, an error occurs.
0: Setting of write data address is normal
1: Setting of write data address is abnormal
