7. Perform one auto-program operation for a 128-byte block for each address. Two or more
additional programming operations cannot be performed on a previously programmed address
block.
8. Confirm normal end of auto-programming by checking I/O6. Alternatively, status read mode
can also be used for this purpose (I/O7 status polling is used as the auto-program operation end
decision pin).
9. Status polling I/O6 and I/O7 pin information is retained until the next command write. As long
as the next command write has not been performed, reading is possible by enabling CE and
OE.
