DDI0_DDC_AUX_SEL B95 Selects the function of DDI1_CTRLCLK_AUX+ and

DDI1_CTRLDATA_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.

center tap. The reference voltage is determined by the requirements of the

Module PHY and may be as low as 0V and as high as 3.3V. The reference

voltage output shall be current limited on the Module. In the case in which

the reference is shorted to ground, the current shall be 250 mA or less.
