1. A touch sensing device comprising:
a first circuit configured to transmit a first uplink signal based on a first protocol in a first frame and to transmit a second uplink signal based on a second protocol that is different from the first protocol in a second frame that is subsequent to the first frame; and
a second circuit configured to receive a first downlink signal corresponding to the first uplink signal according to a downlink signal timing based on the first protocol in the first frame and to receive a second downlink signal corresponding to the second uplink signal according to a downlink signal timing based on the second protocol in the second frame.
