Abstract
A communication interface device includes: a first interface circuit including a chip select terminal connected to a first terminal, a clock terminal connected to a second terminal, and a data terminal connected to a third terminal; and a second interface circuit including a second clock terminal connected to the first terminal and a data terminal connected to the third terminal. In a case of performing communication by the first interface circuit, a fixed signal fixed at a predetermined level is input into the first terminal, a clock signal is input into the second terminal, and a data signal is input into the third terminal, and in a case of performing communication by the second interface circuit, the clock signal is input into the first terminal and the data signal is input into the third terminal.
