    摘要： This invention offers an LCD drive circuit that prevents conversion to a wrong duty driving state and an unintended display caused by taking in of serial data corresponding to the wrong duty driving state. The LCD drive circuit is provided with an LCD drive signal generation circuit that generates driving signals to turn LCD segments on and off based on serial data received by a serial data receiving circuit and is switchable between a ¼ duty driving state and a ⅓ duty driving state. The LCD drive circuit is also provided with a driving state setting circuit that sets the LCD drive signal generation circuit to the ¼ duty driving state based on identification data when the serial data receiving circuit receives the serial data corresponding to the ¼ duty driving state and thereafter forbids the LCD drive signal generation circuit to take in serial data corresponding to the ⅓ duty driving state when the serial data receiving circuit receives the serial data corresponding to the ⅓ duty driving state.

    摘要： This invention offers a data communication system that can perform data communication and detection of a data read-in request signal while reducing the number of communication lines to three, and is tolerant of noise. The data communication between a microcomputer and a key scan IC and the detection of the data read-in request signal are performed through a control line, a clock line and a data line. The data communication system is provided with a data line control circuit that controls the data line so that outputting of the data read-in signal RDRQ to the data line is disabled when first command data is inputted to the key scan IC through the data line, and that the outputting of the data read-in request signal RDRQ to the data line is enabled when second command data is inputted from the microcomputer to the key scan IC through the data line.
