Classification: CPC H | IPC H

Claim 9:
10. The integrated circuit according to claim 9, wherein
the control unit is configured to: (i) receive the first signal from the signal input part while stopping the output of the signal output part; (ii) after receiving the first signal, output from the signal output part the second signal whose logic level is different from that of the first signal; (iii) after the second signal is output, stop the output of the signal output part; (iv) after the predetermined time length has elapsed after the output of the signal output part is stopped, receive the third signal from the signal input part; (v) after a predetermined time length has elapsed after the third signal is received, receive a fourth signal; and (vi) store in the storage the setting condition which is a 2 or more-bit setting condition per the terminal determined based on potentials of the received first, third, and fourth signals, wherein the third signal has characteristics in which, the greater the resistance value of the one of the pull-up resistor and the pull-down resistor that is selectively connected to the terminal, the smaller the change in the potential according to the elapsed time after the second signal is output, and wherein the fourth signal has characteristics in which, the greater the resistance value of the one of the pull-up resistor and the pull-down resistor that is selectively connected to the terminal, the smaller the change in the potential according to the elapsed time after the second signal is output.
