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

A control method for a semiconductor device comprising an interface circuit, initial settings, an initialization function stored in a mask ROM (Read Only Memory), a CPU (Central Processing Unit), and non-volatile memory,

• wherein the CPU sets the initial settings in the interface circuit by executing the initialization function during initialization, and in setting the initial settings in the interface circuit, the CPU reads address information of the target storage area, data information, and processing content information written in the non-volatile memory, and updates the initial settings set in the interface circuit during initialization by executing the patch function included in the initialization function using the information read from the non-volatile memory.

A control program that enables a computer to execute control processing of a semiconductor device comprising an interface circuit, initial setting values, an initialization function stored in a mask ROM (Read Only Memory), and non-volatile memory,

• wherein the computer executes the process of setting the initial setting values in the interface circuit by executing the initialization function during initialization,
• wherein the computer reads address information of the storage area to be accessed, data-related information, and processing-related information, which are written in the non-volatile memory, in the process of setting the initial setting values in the interface circuit,
• wherein the computer executes a patch function included in the initialization function using the information read from the non-volatile memory and updates the initial setting values set in the interface circuit during initialization.
