Notes:
1. Not 100% tested.
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.
6. 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.
