Reprogram Data Computation Table
Notes: 1. Data transfer is performed by byte transfer. The lower 8 bits of the first address written to must be

2. Verify data is read in 16-bit (word) units.
3. Reprogram data is determined by the operation shown in the table below (comparison between the data
4. A 128-byte area for storing program data, a 128-byte area for storing reprogram data, and a 128-byte area for storing additional-programming data must be provided in RAM.
5. A write pulse of 30 s or 200 s is applied according to the progress of the programming operation. See Note 6 for details of the pulse widths.

in this case, H'FF data must be written to the extra addresses.
stored in the program data area and the verify data). Bits for which the reprogram data is 0 are programmed in the next reprogramming loop.
Therefore, even bits for which programming has been completed will be subjected to programming once again if the result of the subsequent verify operation is NG.
The contents of the reprogram data area and additional-programming data area are modified as programming proceeds.
When writing of additional-programming data is executed, a 10 s write pulse should be applied. Reprogram data X' means reprogram data when the write pulse is applied.

Note: Use a 10 s write pulse for additional programming.
