Notes:
1. Word count values on DQ
register. Count ranges for this device are N=0000h to 01FFh.
2. The device outputs the Status Register when read.
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 Buffered Program command if the
current address is outside the original block address .
6. The Status register indicates an “improper command
Sequence” if the Buffered Program command is aborted.
Follow this with a Clear Status Register command .
7. The device defaults to output SR data after the Buffered
Programming Setup Command (E8h) is issued . CE# or OE#
must be be toggled to update Status Register . Don’t issue the
Read SR command (70h), which would be interpreted by the
internal state machine as Buffer Word Count.
8. 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.
