    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.
