1. Selection of on-chip program to be downloaded and setting of download destination
This LSI has programming/erasing programs and they can be downloaded to the on-chip RAM.
The on-chip program to be downloaded is selected by setting the corresponding bits in the
programming/erasing interface register. The download destination can be specified by FTDAR.
2. Download of on-chip program
The on-chip program is automatically downloaded by setting the SCO bit in the flash key code
register (FKEY) and the flash code control and status register (FCCS), which are programming/
erasing interface registers.
The user MAT is replaced to the embedded program storage area when downloading. Since the
flash memory cannot be read when programming/erasing, the procedure program, which is
working from download to completion of programming/erasing, must be executed in a space other
than the flash memory to be programmed/erased (for example, on-chip RAM).
Since the result of download is returned to the programming/erasing interface parameters, whether
the normal download is executed or not can be confirmed.
