Question:

What happens if SHE accesses to WorkFLASH while write or erase to WorkFLASH is in progress?

Answer:

The arbiter in WorkFLASH evaluates arbitration according to the round-robin scheme between two bus interfaces WorkFLASH interface (WFIF) and SHE interface (SHEIF). Thus, SHE access by SHEIF is stalled until writing or erasing to WorkFLASH has finished.
For more details, see the “Secure Hardware Extension (SHE) Support” section in the corresponding hardware manual:
