The DisplayPort 1.4 TX Subsystem supports the following eDP features:
  • Reduced AUX timing because the AUX sync patterns are reduced from 16 pulses to 8 pulses
  • Alternate Scrambler Seed Reset (ASSR)
    Note: Offset 0x08C bit-0 has been set to enable the ASSR method for content protection in the DP source. This is the R/W register from the AXI4 interface.
  • Enhanced Framing

eDP can be enabled by using the following Tcl command:

set_property -dict [list CONFIG.EDP_ENABLE {true}] [get_bd_cells v_dp_txss1_0] 

When generating the subsystem, if EDP_ENABLE is set to true, the Version register, (Offset 0x0F8) Bits [7:0] - Internal Revision is updated with 0x01.

Note: The eDP feature uses the same hardware infrastructure (connector, FMC/PCB, pinouts) of the regular DisplayPort 1.4.
