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

Abstract

To provide a semiconductor device, a control method for the semiconductor device, and a control program that can update the initial setting values of the interface circuit after a mask ROM is implemented. The semiconductor device includes an interface circuit, the mask ROM storing initial setting values and an initialization function, a CPU (Central Processing Unit) that sets the initial setting values in the interface circuit by executing the initialization function during initialization, and non-volatile memory. The initialization function stored in the mask ROM includes a patch function that updates the initial setting values set in the interface circuit during initialization using address information of the storage area to be accessed, data-related information, and processing-related information, which are written in the non-volatile memory.
