8.1 System Interface using CE# don't care
To simplify system interface, CE# may be un-asserted during data loading or sequential data-reading as shown below. By
operating in this way, it is possible to connect NAND Flash to a microprocessor.
Contrary to standard Nand, CE# don't care devices do not allow sequential read function.
