■ Ongoing communication (TCP/IP, FTP, HTTP, SBUS Serial, MCx serial commu-nication, USB).■ XOB execution■ Asynchronous CSF background execution■ Other internal tasks execution / internal events■ Device type (PCD7.R5xx or PCD7.R600 – SD cards).More over, for the same CSF call, the execution time may vary a lot. For example, the S.File.Delete CSF call will take more time if a directory is given as argument (many sub-directories, each of them containing many files) or if a file is given as argument.For all these reasons, it is impossible to provide precise execution time for the file system CSF.However, an indication can be provided, which has been measured within the follow- ing condition:■ HTTP, FTP and TCP/IP communication are inactive■ No serial communication is active■ In order to start / stop the timing measurements, a PG communication overUSB is established, with a very low communication rate (lowest) and only one variable (FLAG) is refreshed.
