Programming/erasing of the flash memory is done by downloading an on-chip
programming/erasing program to the on-chip RAM and specifying the start address of the
programming destination, the program data, and the erase block number using the
programming/erasing interface registers and programming/erasing interface parameters.
The procedure program for user program mode/user boot mode is made by the user. Figure 24.5
shows the procedure for creating the procedure program. For details, see section 24.8.2, User
Program Mode, section 24.8.3, User Boot Mode.
