Selects the function of DDI1_CTRL 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.

Reference voltage for Carrier Board Ethernet channel 1 and 2 magnetics
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.
