NOTES :
1. Byte or word count values on DQ
0-7
are loaded into the
count register.
2. Write buffer contents will be programmed at the start
address.
3. Align the start address on a write buffer boundary for
maximum programming performance.
4. The device aborts the Multi Word/Byte Write command
if the current address is outside of the original block address.
5. The status register indicates an "improper command
sequence" if the Multi Word/Byte Write command is aborted.
Follow this with a Clear Status Register command.
SR full status check can be done after each multi word/byte
write or after a sequence of multi word/byte writes.
Write FFH after the last multi word/byte write operation to
place device in read array mode.
