1. An apparatus for transmitting data based on serial communication, the apparatus comprising:
a master apparatus configured to generate an input data packet including first data, second data, and control data; and
a slave apparatus group consisting of a plurality of slave apparatuses connected in a daisy-chain manner to the master apparatus,
wherein the plurality of slave apparatuses are configured to sequentially generate output data packets based on the input data packet from the master apparatus, and a last output data packet output from a last slave apparatus of the plurality of slave apparatuses is output to the master apparatus, and
wherein each of the slave apparatuses determines first identification information (ID), which is ID thereof, using a most significant bit (MSB) among bits included in the first data, extracts second ID, which is ID of the slave apparatus to process the control data, from the second data, and controls a target device connected to the slave apparatus, using the control data when the first ID and the second ID match.
