Notes:
1. Not 100% tested.
6. AC Specifications listed are tested with VIO = VCC. Contact AMD
for information on AC operation with VIO VCC
7. When using the program suspend/resume feature, if the
suspend command is issued within tPOLL, tPOLL must be fully
re-applied upon resuming the programming operation. If the
suspend command is issued after tPOLL, tPOLL is not required
again prior to reading the status bits upon resuming.

.
2. See the “Erase and Programming Performance” section for more
information.
3. For 1–16 words/1–32 bytes programmed.
4. Effective write buffer specification is based upon a
16-word/32-byte write buffer operation.
5. Word/Byte programming specification is based upon a single
word/byte programming operation not utilizing the write buffer.
