⎯ Programming finished processing should be poerformed immediately after programming of

Before reprogramming erased blocks containing a programming

16. Determine the FPFR (general-purpose register R0L) value returned by the programming
program.
17. After programming finishes, clear FKEY and specify software protection.
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) that is at least as long as normal 100 μs.
