Semiconductor device, method for controlling a semiconductor device and control program

Abstract

A semiconductor device, a control method for the semiconductor device, and a control program are provided that can update the initial settings of the interface circuit after a mask ROM has been implemented. The semiconductor device comprises an interface circuit, a mask ROM that stores the initial settings and an initialization function, a CPU (Central Processing Unit) that sets the initial settings in the interface circuit by executing the initialization function during initialization, and non-volatile memory.The initialization function, which is stored in the mask ROM, includes a patch function which updates the initial settings set in the interface circuit during initialization using address information of the memory area to be accessed, information relating to data, and information relating to processing written to the non-volatile memory.
