Section 20 Flash Memory
(a) Download pass/fail result parameter (DPFR: single byte of start address specified by
This parameter indicates the return value of the download result. The value of this parameter can
be used to determine if downloading is executed or not. Since the confirmation whether the SCO
bit is set to 1 is difficult, the certain determination must be performed by writing the single byte of
the start address specified by FTDAR to the value other than the return value of download (for
example, H'FF) before the download start (before setting the SCO bit to 1).

Source Select Error Detect
Only one type for the on-chip program which can be
downloaded can be specified. When more than two types
of the program are selected, the program is not selected,
or the program is selected without mapping, error is
occurred.
0: Download program can be selected normally
1: Download error is occurred (multi-selection or program
Flash Key Register Error Detect (FK)
Returns the check result whether the value of FKEY
register is set to H'A5.
0: FKEY setting is normal (FKEY = H'A5)
1: Setting value of FKEY becomes error (FKEY = value
Success/Fail
Returns the result whether download is ended normally or
not. The determination result whether program that is
downloaded to the on-chip RAM is read back and then
transferred to the on-chip RAM is returned.
0: Downloading on-chip program is ended normally (no
1: Downloading on-chip program is ended abnormally
