The procedures for download, initialization, and erasing are shown in figure 21.12.
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 21.4.4, Procedure Program and Storable Area for
Programming Data.
For the downloaded on-chip program area, refer to figure 21.10.
