As soon as the discovery is finished by the HPD detection, the configuration data is
exchanged between a source and sink through the I
DDC interface is ready for communication as soon as the power supply to the chip is
present and stable. When the desired port is enabled and the chip is out of shutdown mode,

Thus, as soon as the HPD detection sequence is complete, the DDC interface can be
readily used. There is no delay between the HPD detection and I
