Abstract:
1. A serial data transfer method of serially transferring a data signal from a first electric device to a second electric device in synchronization with a clock signal and a strobe signal, the data signal being supplied from the first electric device to the second electric device using a first signal line, the clock signal being supplied from the first electric device to the second electric device using a second signal line, and the strobe signal being supplied from the first electric device to the second electric device using a third signal line, the method comprising: an input step of: a capturing step of selectively capturing the first portion of the data signal inputted to the shift register by a first latch or a second latch of a plurality of latches, where the first latch and the second latch are connected to the shift register in parallel, based on a result of a logical operation of a signal level in the strobe signal and the predetermined signal level in the second portion of the data signal by the logic circuit when or after the strobe signal is supplied from the first electric device to the second electric device, wherein the predetermined signal level is either a high level or a low level.
