Notes:
1. Not 100% tested.
2. See the “Erase And Programming Performance” section for more information.
3. For 1–16 words (or 1–32 bytes in byte mode) programmed.
4. Effective write buffer specification is based upon a 16-word (or 32-byte) write buffer operation.
5. Word/Byte programming specification is based upon a single word/byte programming operation not utilizing the write buffer.
