1. In order to activate the DDC lines functional block, the three following conditions have to be met:

•

VDD_5V has to reach the VDD_ON threshold

•

The inputs and outputs of the bidirectional level shifters must be set to a high level after the power-on

•

The HPD line has to be activated one time
