Detailed operation

8. The MCU cannot invoke these instructions while executing code from the same Flash memory as that for which the

instruction is intended. The MCU must fetch, for example, the code from the secondary Flash memory when reading the

Sector Protection Status of the primary Flash memory.

9. Additional sectors to be erased must be written at the end of the Sector Erase instruction within 80 µs.

10. The system may perform READ and Program cycles in non-erasing sectors, read the Flash ID or read the Sector Protection

Status when in the Suspend Sector Erase mode. The Suspend Sector Erase instruction is valid only during a Sector Erase

cycle.

11. The Resume Sector Erase instruction is valid only during the Suspend Sector Erase mode.

12. The Unlock Bypass instruction is required prior to the Unlock Bypass Program instruction.

13. The Unlock Bypass Reset Flash instruction is required to return to reading memory data when the device is in the Unlock

Bypass mode.
