Hi there
A quick question as below from our customer：
When can the software judge (sel1 or sel2) to switch to A chanel or B chanel? Is the TS3DV642 HPD first detected (HPD_A or HPD_B) that there is a level change to switch A Chanel or B chane?
If the A port is inserted into the DP device, the HPD_A port detects a high level insertion, and then HPD_A is connected to the HPD, and this signal is transmitted to the HPD on the DP ic.
If the A port is inserted into the DP device (there is no HPD pin), the HPD_A port will not detect the signal insertion. At this time, the HPD_A and the HPD are not connected, and the data will not be switched to the A Chanel.
