(c) Flash pass/fail parameter (FPFR: general register R0L of CPU)
This parameter indicates the return value of the program processing result.

Value
R/W Description
7 ⎯ ⎯ ⎯ Unused
Return 0.
6 MD ⎯ R/W Programming Mode Related Setting Error Detect
Returns the check result that the error protection state is
not entered. When the error protection state is entered, 1
is written to this bit. The state can be confirmed with the
FLER bit in FCCS. For conditions to enter the error
protection state, see section 21.5.3, Error Protection.
0: FLER setting is normal (FLER = 0)
1: Programming cannot be performed (FLER = 1)
5 EE ⎯ 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.
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 PROM
mode.
0: Programming has ended normally
1: Programming has ended abnormally (programming
result is not guaranteed)
4 FK ⎯ 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 ⎯ ⎯ ⎯ Unused
Returns 0.
