R/W Description
5
EE
Undefined 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 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.
0: Programming has ended normally
1: Programming has ended abnormally (programming
result is not guaranteed)
4
FK
Undefined 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)
3

Undefined R/W Unused
Return 0.
2
WD
Undefined R/W Write Data Address Error Detect
When an 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
1
WA
Undefined R/W Write Address Error Detect
When the following items are specified as the start
address of the programming destination, an error
occurs.
• The programming destination address is an area
other than flash memory
• The specified address is not at the 128-byte
boundary (A6 to A0 are not 0)
0: Setting of programming destination address is normal
1: Setting of programming destination address is
abnormal
