10. A non-transitory computer readable medium storing a program that causes a computer to execute functions of:

executing a program;

setting a first storage area which stores the program and a second storage area which stores data generated by the execution of the program in a first non-volatile memory which is readable and writable and is capable of retaining stored information even when no power is supplied;

connecting the computer to the first non-volatile memory; and

storing conditions which are set to transmit and receive the program and the data to and from the first non-volatile memory in a second non-volatile memory which is readable and writable and is capable of retaining stored information even when no power is supplied, the conditions include maximum available clock frequency or signal timing.

11. The non-transitory computer readable medium storing the program according to claim 10 ,

wherein the program causes the computer to further execute a function of:

setting, as the set conditions, communication conditions for communication with the first non-volatile memory before connection to the first non-volatile memory, and

in the function of storing the set conditions, the communication conditions are stored as the set conditions in a second non-volatile memory.

12. An information processing method comprising:

executing a program;

setting a first storage area which stores the program and a second storage area which stores data generated by the execution of the program in a first non-volatile memory which is readable and writable and is capable of retaining stored information even when no power is supplied;
