System Design Note: If the RY / BY pin signals from multiple devices are wired together as shown in the
diagram, the Status Read function can be used to determine the status of each individual device.
Reset
The Reset mode stops all operations. For example, in case of a Program or Erase operation, the internally
generated voltage is discharged to 0 volt and the device enters the Wait state.
Reset during a Cache Program/Page Copy may not just stop the most recent page program but it may also
stop the previous program to a page depending on when the FF reset is input.
The response to a “FFh” Reset command input during the various device operations is as follows:
