DDI1_HPD
C24
Multiplexed with DP1_HPD and HDMI1_HPD
DDI1_CTRLCLK_AUX+
D15
Multiplexed with DP1_AUX+ and HMDI1_CTRLCLK
DP AUX+ function if DDI1_DDC_AUX_SEL is no connect
HDMI/DVI I2C CTRLCLK if DDI1_DDC_AUX_SEL is pulled high
DDI1_CTRLDATA_AUX-
D16
Multiplexed with DP1_AUX- and HDMI1_CTRLDATA
DP AUX- function if DDI1_DDC_AUX_SEL is no connect
HDMI/DVI I2C CTRLDATA if DDI1_DDC_AUX_SEL is pulled high
DDI1_DDC_AUX_SEL
D34
Selects the function of DDI1_CTRLCLK_AUX+ and DDI1_CTRLDATA_AUX-
This pin shall have a IM 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 CTRLCLK and CTRLDATA signals.

Multiplexed with DP2_HPD and HDMI2_HPD
DDI2_CTRLCLK_AUX+
C32
Multiplexed with DP2_AUX+ and HDMI2_CTRLCLK
DP AUX+ function if DDI2_DDC_AUX_SEL is no connect
HDMI/DVI I2C CTRLCLK if DDI2_DDC_AUX_SEL is pulled high
DDI2_CTRLDATA_AUX-
C33
Multiplexed with DP2_AUX- and HDMI2_CTRLDATA
DP AUX- function if DDI2_DDC_AUX_SEL is no connect
HDMI/DVI I2C CTRLDATA if DDI2_DDC_AUX_SEL is pulled high
DDI2_DDC_AUX_SEL
C34
Selects the function of DDI2_CTRLCLK_AUX+ and DDI2_CTRLDATA_AUX-
This pin shall have a IM 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 CTRLCLK and CTRLDATA signals.
