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 is made by the user. Figure 20.5 shows the
procedure for creating the procedure program. For details, see section 20.7.3, User Program Mode.
(1)
This LSI has programming/erasing programs which can be downloaded to the on-chip RAM. The
on-chip program to be downloaded is selected by the programming/erasing interface registers. The
start address of the on-chip RAM where an on-chip program is downloaded is specified by the
flash transfer destination address register (FTDAR).
