(d) The return value in the erasing program, FPFR (general register R0L) is judged.
(e) Determine whether erasure of the necessary blocks has finished.
(f) After erasure finishes, clear FKEY and specify software protection.
(4) 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 18.13 shows an example of repetitively executing RAM emulation, erasing, and
programming.
Figure 18.13 Sample Procedure of Repeating RAM Emulation, Erasing, and Programming
If more than one block is to be erased, update the FEBS parameter and repeat steps (b) and (c).
Blocks that have already been erased can be erased again.
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 s.
