DATA_AUX-. 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

USB over-current sense, USB channels 0 and 1. A pull-up for this
line shall be present on the Module. An open drain driver from a
USB current monitor on the Carrier Board may drive this line low. Do
not pull this line high on the Carrier Board.
