A communication control method according to the present invention is a communication control method for a communication system using a common AC coupling element for transmitting and receiving signals between first and second circuits, the method including: setting a first transmission circuit Tx1 to a valid state and a second reception circuit Rx2 to an invalid state; setting a second transmission circuit Tx2 to the invalid state and a first reception circuit Rx1 to the valid state; transmitting signals from the first transmission circuit Tx1 to the first reception circuit Rx1 through the AC coupling element; setting the first transmission circuit Tx2 to the invalid state and the second reception circuit Rx2 to the valid state during an interval time period after transmission of signals by the first transmission circuit Tx1; setting the second transmission circuit Tx2 to the valid state and the first reception circuit Rx1 to the invalid state during the interval time period; and transmitting signals from the second transmission circuit Tx2 to the second reception circuit Rx2 through the AC coupling element during the interval time period. This prevents a crosstalk between transmission and reception signals with a small circuit. |
