Section 20 Flash Memory
(m) The return value in the programming program, FPFR (general register R0L) is determined.
(n) Determine whether programming of the necessary data has finished.
(o) After programming finishes, clear FKEY and specify software protection.
(3)

⎯ Since the stack area is used in the programming program, a stack area of a maximum 128
If more than 128 bytes of data are to be programmed, specify FMPAR and FMPDR in 128-
byte units, and repeat steps (l) to (n). 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.
If this LSI is restarted by a power-on reset immediately after user MAT programming has
finished, secure a reset period (period of RES = 0) of 100 μs or longer, which is longer than
usual.
