             When I  power up and  initialize the ADV7513  after connect the display device,all is  OK,ADV7513 reads data through DDC bus ,ADV 7513 output HDMI CLK AND DATA,Then,I  hot swap  the  HDMI line,ADV 7513 is  no  output。I  find  the HPD signal is HIGN, ADV7513 does not read DDC data,no  HDMI CLK AND DATA output。if I Reconfiguration  ADV7513,all is OK. Why is that so?
