b. After write pulse application, a verify-read is performed in program-verify mode, and
c. If programming of other bits is incomplete in the 128 bytes, reprogramming process should
changed according to the degree of progress through the program/program-verify
procedure. For detailed wait time specifications, see section 21.1.6, 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
below.
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.
loops in reprogramming processing is guaranteed not to exceed the maximum value of 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.
be executed. If a bit for which programming has been judged to be completed is read as 1
in a subsequent verify-read, a write pulse should again be applied to that bit.
* Additional programming processing is necessary only when the reprogramming loop
count (n) is 1 to 6.
