<P>PROBLEM TO BE SOLVED: To provide a data transfer controller capable of efficiently transmitting a vertical synchronization signal which is output from a display driver to an opposite party device and an electronic apparatus including the data transfer controller. <P>SOLUTION: The data transfer controller is constituted of a link controller 100 for analyzing a packet received from a host side and generating a packet to be transmitted to the host side; and a signal detecting circuit 360 for receiving the vertical synchronizing signal output from a display driver 6 via an interface circuit 110 and outputting a detection signal. When a read request packet requesting the reading of status of the vertical synchronizing signal is received and the detection signal is output, the link controller 100 performs processing for transmitting a response packet or an acknowledge packet to the host side. <P>COPYRIGHT: (C)2009,JPO&INPIT |
