ABSTRACT:
Serial data transfer method, electric device and printing apparatus for enabling various controls without adding signal lines and control signals to serial data transfer utilizing, e.g., three signal lines for transferring a data signal, a clock signal, and a strobe signal. According to this method, when a data signal, which is supplied from a first electric device to a second electric device using a first signal line, is serially transferred from the first electric device to the second electric device in synchronization with a clock signal which is similarly supplied through a second signal line, the data signal is inputted to a shift register of the second electric device in synchronization with the clock signal, and the data signal inputted to the shift register is captured by plural latches of the second electric device utilizing at least one of the control signal supplied from the first electric device to the second electric device using a third signal line, a signal level of the data signal, and a signal level of the clock signal.
