[15] After programming finishes, clear FKEY and specify software protection.
Erasing Procedure in User Program Mode: The procedures for download, initialization, and
erasing are shown in figure 17.71.
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 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 17.29.3, Procedure Program and Storable Area for
Programming Data.
For the downloaded on-chip program area, refer to the RAM map for programming/erasing in
figure 17.69.
If this LSI is restarted by a power-on reset immediately after user MAT programming has
finished, secure a reset period (period of RES = 0) that is at least as long as normal 100 μs.
