Information terminal, information processing system, and methods of controlling the same

摘要

An information terminal disclosed herein includes a data storage in which data is stored; an internal controller which accesses the data storage by a request from inside the information terminal; and an external controller which accesses the data storage by a request from outside the information terminal. If a request that the internal controller access the data storage is generated while the external controller is accessing the data storage, then the external controller repeatedly transmits a negative reply that data has not been properly received in response to access from the outside and the internal controller accesses the data storage while the external controller repeatedly transmits the negative reply.
