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 20.4.4, Procedure Program and Storable Area for
Programming Data.
For the downloaded on-chip program area, see the RAM map for programming/erasing in figure
20.10.
A single divided block is erased by one erasing processing. For block divisions, see figure 20.4.
To erase two or more blocks, update the erase block number and perform the erasing processing
for each block.
