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.
NOTE:
1. Byte or word count values on DQ0–DQ7 are loaded into the 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., A4–A0 of the start
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.
7. Toggling OE# (LOW to HIGH to LOW) updates the status register. This can be done in place of issuing the READ STATUS
REGISTER command.
