Claim 5:
6. The integrated circuit according to claim 5, 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 the first signal is received, 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; and (v) store in the storage the setting condition which is a 2-bit setting condition obtained by a combination of one bit according to a potential of the received first signal and another bit according to a potential of the received third signal, 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 outputting the second signal.
