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.
Claims16
A signal interface system, comprising:
- a data line;
- a clock line;
- a master circuit having a main data pin coupled to the data line and a main clock pin coupled to the clock line;
- and
- at least one slave circuit, each having a secondary data pin coupled to the data line and having a secondary clock pin coupled to the clock line;
- wherein 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,
- wherein the master circuit provides a data signal to the data line through the main data pin to transmit the main control data, and the master circuit provides a clock signal to the clock line through the main clock pin to transmit the additional control data,
- wherein a determination method of respective logic levels of a plurality of data bits of the main control data according to the data signal is different from a determination method of respective logic levels of a plurality of data bits of the additional control data according to the clock signal.
A data transmission method of a signal interface system, wherein the signal interface system comprises a master circuit and at least one slave circuit, the data transmission method comprising:
- transmitting a main control data to the at least one slave circuit through the master circuit and a data line;
- and
- transmitting an additional control data to the at least one slave circuit through the master circuit and a clock line,
- wherein the main control data is transmitted through a data signal on the data line, and the additional control data is transmitted through a clock signal on the clock line,
- wherein a determination method of respective logic levels of a plurality of data bits of the main control data according to the data signal is different from a determination method of respective logic levels of a plurality of data bits of the additional control data according to the clock signal.
