ABSTRACT:
A switch section for changing the function of an FPGA is provided with a data latch circuit used for connection control. The data latch circuit includes program sections in which program data is stored in advance, and latch unit. At the time of changing the function, control signals are selectively inputted, whereby latch unit and program section are electrically coupled to each other, and a data signal stored in program section is outputted from the data latch circuit. With this arrangement, it is possible to easily change the function of an FPGA without rewriting program data.
