Section 25 Flash Memory
25.8.3
Programming/erasure of the user MAT is executed by downloading an on-chip program. The user
boot MAT cannot be programmed/erased in user program mode. The programming/erasing flow is
shown in figure 25.11.
Since high voltage is applied to the internal flash memory during programming/erasure, a
transition to the reset state or hardware standby mode must not be made during
programming/erasure. A transition to the reset state or hardware standby mode during
programming/erasure may damage the flash memory. If a reset is input, the reset must be released
after the reset input period (period of RES = 0) of at least 100 μs.

Exit RAM emulation mode beforehand. Download is not allowed
in emulation mode.
When the program data is adjusted in emulation mode, select
the download destination specified by FTDAR carefully. Make
sure that the download area does not overlap the emulation
area.
Programming/erasing is executed only in the on-chip RAM.
After programming/erasing is finished, protect the flash memory
by the hardware protection.
