ABSTRACT:
A multifunctional integrated electronic product including a main microcomputer and a sub microcomputer configured as master and slave, respectively, is capable of preventing a malfunction caused by an error of data transmission between the microcomputers, and a method for the same. A main microcomputer generates control data for controlling the sub microcomputer function and generates following data when no errors are detected in the control data. The main microcomputer checks for a data receipt confirmation signal fed back from the sub microcomputer when there are no errors in the control signal. The absence of the data receipt confirmation signal causes the main microcomputer to repeatedly generate the same control data. When an error in the control data is detected by the sub microcomputer, the data receipt confirmation signal is not sent and an error generating signal is sent to the main microcomputer which causes the same to repeatedly generate the control data.
