COMMUNICATION METHOD AUTOMATICALLY INCREMENTING IDs OF ICs HAVING DAISY CHAIN CONNECTION STRUCTURE, AND IC COMMUNICATION DEVICE PERFORMING THE METHOD

A communication method automatically incrementing IDs of ICs, as a method of performing IC communication by an IC communication device including first to N-th ICs arranged to be adjacent (N is an integer equal to or greater than 2), the method comprising:

• a first transmission step of transmitting a wakeup signal to the first IC, by the IC communication device;
• a second transmission step of simultaneously transmitting the wakeup signal transmitted at the first transmission step in two directions to a controller and the second IC arranged to be adjacent to the first IC, by the IC communication device;
• a third transmission step of simultaneously transmitting the wakeup signal transmitted at the second transmission step in two directions to the first IC and the third IC arranged to be adjacent to the second IC, by the IC communication device;
• and
• a step of simultaneously transmitting the wakeup signal transmitted at the third transmission step in two directions to two ICs arranged to be adjacent among the third to N-th ICs, by the IC communication device.
