Notes:
1. DQ5 switches to ‘1’ when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further
3. When reading write operation status bits, the system must always provide the bank address where the Embedded
4. The system may read either asynchronously or synchronously (burst) while in erase suspend.
5. The RDY pin acts a dedicated output to indicate the status of an embedded erase or program operation is in progress. This
6. When the device is set to Asynchronous mode, these status flags should be read by CE# toggle.
