3.2.3.9 Embedded Display Port (eDP) signals

As described in the previous paragraph, the AMD G-Series SOCs offer two multi-purpose Digital Display Interfaces, which allow the implementation of HDMI/DVI,

Display Port (DP) or embedded Display Port (eDP).

When the board is not configured with the eDP-to-LVDS bridge, the on the golden edge card connector is available an eDP interface (derived from AMD G-Series

SOCs Digital Display Interface #0), which allows supporting displays with a resolution up to 2560 x 1600 @ 60Hz.

Here following the signals related to eDP management:

eDP0_TX0+/eDP0_TX0-: eDP channel differential data pair #0.

eDP0_TX1+/eDP0_TX1-: eDP channel differential data pair #1.

eDP0_TX2+/eDP0_TX2-: eDP channel differential data pair #2.

eDP0_TX3+/eDP0_TX3-: eDP channel differential data pair #3.

eDP0_AUX+/eDP0_AUX-: eDP channel differential auxiliary channel.

eDP0_HPD#: eDP channel Hot Plug Detect. Active Low Signal, +3.3V_S electrical level input with 100kΩ pull-up resistor.

LVDS_PPEN: +3.3V_S electrical level output, Panel Power Enable signal. It can be used to turn On/Off the connected display.

LVDS_BLEN: +3.3V_S electrical level output, Panel Backlight Enable signal. It can be used to turn On/Off the backlight's lamps of connected display.

LVDS_BLT_CTRL: this signal can be used to adjust the panel backlight brightness in displays supporting Pulse Width Modulated (PWM) regulations.
