DDI Signals Descriptions
DDI2_HPD D44 I CMOS 3.3V / 3.3V PD 1M and Connect to device Hot Plug Detect DDI Hot-Plug Detect
DDI2_DDC_AUX_SEL C34 I CMOS 3.3V / 3.3V PD 1M to GND NA
Selects the function of DDI2_CTRL and DDI2_CTRLDATA_AUX-.
DDI[n]_DDC_AUX_SEL shall be pulled to 3.3V on the Carrier with a 100K Ohm
resistor to configure the DDI[n]_AUX pair as the DDC channel.
Carrier DDI[n]_DDC_AUX_SEL should be connected to pin 13 of the DisplayPort
