<p>In a programmable input/output circuit connected to an input terminal or an output terminal of an integrated circuit, a desirable combination from signals including a signal of the input terminal (1), an input or output signal of a storage element (2, 3, 4), an input or output signal of a combinational logic circuit (15), and input or output signal of another selector and the like is selected by use of at least one programmable selector (6, 7, 8, 9, 10, 11, 12, 14), processed and output into the output terminal (13), so that an input or output circuit for performing a desirable signal process can be provided. Further, at least one dynamic selector circuit (22) is provided, so that an output signal from another input/output circuit can be input into the storage element (2) and an output signal from the storage element (2) can be supplied to another input/output circuit.</p> |
