The procedures for download of the on-chip program, initialization, and erasing are shown in
figure 24.13.
The procedure program must be executed in an area other than the user MAT to be erased. Setting
the SCO bit in FCCS to 1 to request download must be executed in the on-chip RAM. The area
that can be executed in the steps of the procedure program (on-chip RAM and user MAT) is
shown in section 24.8.4, Storable Areas for On-Chip Program and Program Data. For the
downloaded on-chip program area, see figure 24.11.
