DDI4 - eDP/VGA Port E No
Notes:
1. Port E is bifurcated from eDP, when VGA is used, needs to use available AUX (if HDMI* is in used).
a. For example, DT can use eDP_AUX for VGA converter which is available as free Design but HPD
should be used as DDPE_HPD3.
2. 3xDDC (DDPB, DDPC, DDPD) are valid for all the processor SKUs (for U/Y-Processor Line DDC signals
description, refer to the PCH datasheet (refer Related Document section).
3. 5xHPD (PCH) inputs (eDP_HPD, DDPB_HPD0, DDPC_HPD1, DDPD_HPD2, DDPE_HPD3) are valid for all
processor SKUs.
4. No Port D for U-Processor Line. DDI3_AUX exists as reserved.
5. VBT provides a configuration option to select the four AUX channels A/B/C/D for a given port, based on
how the aux channel lines are connected physically on the board.
