Moreover, an H signal of the AND gate 7 is latched by a DFF 4, and the DFFs 2 and 3 are reset. Along with this, an output of a selector consisting of gates 9, 10 and 11 is changed over to a Q output of the DFF 5-1. Accordingly, a Q output signal of the DFF 5-1 is connected to a D input terminal of a DFF 6, and an output signal of a Q terminal of the DFF 5-1 is latched by the DFF 6 at a rise of a next CLK.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
