20.4.2
The user MAT can be programmed/erased in user program mode. (The user boot MAT cannot be
programmed/erased.)
Programming/erasing is executed by downloading the program in the microcomputer.
The overview flow is shown in figure 20.9.
High voltage is applied to internal flash memory during the programming/erasing processing.
Therefore, transition to reset or hardware standby must not be executed. Doing so may cause
damage or destroy flash memory. If reset is executed accidentally, reset must be released after the
reset input period, which is longer than normal 100 μs.

Programming/erasing is executed only in the on-chip RAM.
However, if program data is in a consecutive area and can be
accessed by the MOV.B instruction of the CPU like SRAM or
ROM, the program data can be in an external space.
After programming/erasing is finished, it must be protected.
