15. After programming finishes, clear FKEY and specify software protection.
If this LSI is restarted by a reset immediately after user MAT programming has finished,
secure the reset period (period of

= 0) of 100
µ
s which is longer than normal.

Figure 25.14 Erasing Procedure
The procedure program must be executed in an area other than the user MAT to be erased.
Especially the part where the SCO bit in FCCS is set to 1 for downloading must be executed in the
on-chip RAM.
The area that can be executed in the steps of the user procedure program (on-chip RAM, user
MAT, and external space) is shown in section 25.4.5, Procedure Program and Storable Area for
Programming Data.
