Abstract
A signal interface system and a data transmission method thereof are provided. The signal interface system includes a data line, a clock line, a master circuit, and at least one slave circuit. The master circuit has a main data pin coupled to the data line and a main clock pin coupled to the clock line. The at least one slave circuit has a secondary data pin coupled to the data line and a secondary clock pin coupled to the clock line. The master circuit transmits a main control data to the at least one slave circuit through the data line, and transmits an additional control data to the at least one slave circuit through the clock line.
