Notes:
1. Not 100% tested.
2. See the 鈥淓rase And Programming Performance鈥?section for more information. Write buffer program is typical per word.
3. For 1鈥?2 bytes programmed.
4. Effective write buffer specification is based upon a 32-byte write buffer operation.
5. Byte programming specification is based upon a single byte programming operation not utilizing the write buffer.
6. 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.
