8. System Interface
To simplify system interface, CE# may be unasserted during data loading or sequential data reading as
shown in
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.
