1. Byte or word count values on DQ
count register. Count ranges on this device for byte mode are
N = 00H to 1FH and for word mode are N = 0000H to 000FH.
2. The device now outputs the status register when read (XSR is
no longer available).
3. Write Buffer contents will be programmed at the device start
address or destination flash address.
4. Align the start address on a Write Buffer boundary for
maximum programming performance (i.e., A
address = 0).
5. The device aborts the Write to Buffer command if the current
address is outside of the original block address.
6. The status register indicates an "improper command
sequence" if the Write to Buffer command is aborted. Follow this
with a Clear Status Register command.
Full status check can be done after all erase and write sequences
complete. Write FFH after the last operation to reset the device to
read array mode.
