1. Word count values on DQ
register. Count ranges for this device are N = 0000h to 0001Fh.
2. The device outputs the status register when read.
3. Write Buffer contents will be written at the device start address or
destination flash address.
4. Align the start address on a Write Buffer boundary for maximum
write performance (i.e., A
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.
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.
