PROBLEM TO BE SOLVED: To provide a data transmission system by which data can be transmitted between a master circuit and a slave circuit at a low cost. SOLUTION: A 1st slave control circuit among n-sets of slave control circuits is connected to a master control circuit 22 to receive a 1st data signal, which decides a 2nd data signal as a function of the 1st data signal and transmits either of the 1st and 2nd data signals as a function of the 1st flag signal. Each (n-2) slave control circuit 26 is connected to a slave control circuit 26 of a pre-stage, receives a data signal sent from the preceding slave controller 26, the succeeding data signal is decided as a functions of the data signal sent from the preceding slave control circuit 26 and either of the data sent from the preceding slave controller 26 and the decided succeeding data signal is transmitted as a function of each flag signal. |
