1. Byte or word count values on DQ0-7 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 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.
