[6] After erasure finishes, clear FKEY and specify software protection.
Erasing and Programming Procedure in User Program Mode: By changing the on-chip RAM
address of the download destination in FTDAR, the erasing program and programming program
can be downloaded to separate on-chip RAM areas.
Figure 17.72 shows an example of repetitively executing RAM emulation, erasing, and
programming.
In the above example, the erasing program and programming program are downloaded to areas
excluding the 4 kbytes (H'FFDC00 to H'FFEC00) from H'FFDC00.
Figure 17.72 Sample Procedure of Repeating RAM Emulation, Erasing, and Programming
If this LSI is restarted by a power-on reset immediately after user MAT erasure has finished,
secure a reset period (period of RES = 0) that is at least as long as normal 100 μs.
