Abstract
PURPOSE: To make it possible to accept easily only one interface IF by controlling a first-come decision gate signal generation circuit, which is provided correspondingly to two interfaces IF, by control signals corresponding to two interfaces IF.
CONSTITUTION: Two IFs A-1 and B-1 are connected to connection circuits 61 and 62 respectively, and control circuit 70 is connected to one of them and is operated. At this time, in the first-come decision circuit for IFs A-1 and B-1, when reset signal R is O, output 106 of delay circuit 6 becomes O after a prescribed delay time, and output 111 of AND circuit 10 becomes 1, and connection request B-2 of IF B-1 becomes operatable. Output 107 becomes 0 after a prescribed time after output 106 of circuit 6 becomes 0, and input 105 to circuit 6 becomes 1, and further, AND gate 9 is operated after a prescribed time, and connection request A-2 becomes operatable. Connection requests A-2 and B-2 are gated by signals 110 and 111 different in phase and can set a connection FF only when connection FFs 14 and 13 in opposite sides are not set.
