Section 25 Flash Memory
25.5
Programming/erasure 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 and user boot mode is made by the user. Figure
25.5 shows the procedure for creating the procedure program. For details, see section 25.8.3, 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).
