This pin shall have a 1M pull-down to
logic ground on the Module. If this input is floating the AUX pair is
used for the DP AUX+/- signals. If pulled-high the AUX pair
contains the CRTLCLK and CTRLDATA signals
************************************************************
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
