Notes:
1. Not 100% tested.
2. See the “Erase And Programming Performance” section for more information.
3. For 1–16 words programmed.
4. Effective write buffer specification is based upon a 16-word write buffer operation.
5. Word programming specification is based upon a single word programming operation not utilizing the write buffer.
6. AC Specifications listed are tested with V_IO = V_CC. Contact AMD for information on AC operation with V_IO ≠ V_CC.
7. When using the program suspend/resume feature, if the suspend command is issued within t_POLL, t_POLL must be fully
re-applied upon resuming the programming operation. If the suspend command is issued after t_POLL, t_POLL is not required
again prior to reading the status bits upon resuming.
