program/program-verify procedure. For detailed wait time specifications, see section
21.2.5, Flash Memory Characteristics.
To cover the points noted above, bits on which reprogramming processing is to be executed,
and bits on which additional programming is to be executed, must be determined as shown in
tables 18.8 and 18.9.
Since reprogram data and additional-programming data vary according to the progress of the
programming procedure, it is recommended that the following data storage areas (128 bytes
each) be provided in RAM.
program/program-verify procedure is completed. In the H8/3052BF, the number of loops
in reprogramming processing is guaranteed not to exceed the maximum programming
count (N).
programming is judged to have been completed for bits read as 0. The following
processing is necessary for programmed bits.
When programming is completed at an early stage in the program/program-verify
procedure:
If programming is completed in the 1st to 6th reprogramming processing loop,
additional programming should be performed on the relevant bits. Additional
programming should only be performed on bits which first return 0 in a verify-read
in certain reprogramming processing.
When programming is completed at a late stage in the program/program-verify procedure:
If programming is completed in the 7th or later reprogramming processing loop, additional
programming is not necessary for the relevant bits.

in a subsequent verify-read, a write pulse should again be applied to that bit.
