Figure 17-78 Programming of the Data After Tuning
[1] After the data to be programmed has fixed values, clear the RAMS bit to 0 to cancel the
overlap of RAM.
[2] Transfer the user programming/erasing procedure program to RAM.
[3] Run the programming/erasing procedure program in RAM and download the on-chip
programming/erasing program.
Specify the download start address with FTDAR so that the tuned data area does not overlap
with the download area.
[4] When the EB0 area of the user MAT has not been erased, the programming program will be
downloaded after erasure. Set the parameters FMPAR and FMPDR so that the tuned data is
designated, and execute programming.
Note: Setting the RAMS bit to 1 puts all the blocks in the flash MAT into a program/erase-
protected state regardless of the values of the RAM2 to RAM0 bits (emulation protection).
In this state, downloading of the on-chip programs is also disabled, so clear the RAMS bit
before actual programming or erasure.

[1] Cancel the emulation mode.
[2] Transfer the user-created program/

[3] Download the on-chip programming/erasing
programs, avoiding the tuning <illegible>
data area set in FTDAR.
[4] Execute programming after erasing,
as necessary.
