12. The return value in the programming program, the FPFR parameter is determined.
13. Determine whether programming of the necessary data has finished. If more than 128 bytes of
data are to be programmed, update the FMPAR and FMPDR parameters in 128-byte units, and
repeat steps 11 to 14. Increment the programming destination address by 128 bytes and update
the programming data pointer correctly. If an address which has already been programmed is
written to again, not only will a programming error occur, but also flash memory will be
damaged.
14. After programming finishes, clear FKEY and specify software protection. If this LSI is
restarted by a reset immediately after programming has finished, secure the reset input period
(period of RES = 0) of at least 100 μs.
