Description
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
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)
Unused
Return 0.
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
Write Address Error Detect
When the following items are specified as the start
address of the programming destination, an error
occurs.

abnormal
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)
