Bit 5-Programming Execution Error Detect (EE): 1 is returned to this bit when the specified
data could not be written because the user MAT was not 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 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 the boot mode or PROM mode.
Bit 5
EE
0
1
Description
Programming has ended normally
Programming has ended abnormally (programming result is not guaranteed)
Bit 4—Flash Key Register Error Detect (FK): Returns the check result of the value of FKEY
before the start of the programming processing.
Bit 4
FK
0
1
Description
FKEY setting is normal (FKEY = H'5A)
FKEY setting is error (FKEY = value other than H'5A)
Bit 3—Unused: Returns 0.
Bit 2—Write Data Address Detect (WD): When flash memory area is specified as the start
address of the storage destination of the program data, an error occurs.
Bit 2
WD
0
1
Description
Setting of write data address is normal
Setting of write data address is abnormal
Bit 1—Write Address Error Detect (WA): When the following area is specified as the start
address of the programming destination, an error occurs.
1. If the start address is outside the flash memory area
2. If the specified address is not a 128-byte boundary (A6 to A0 are not 0)
