1. the Count register.
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.
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.
