The DisplayPort 1.4 TX Subsystem supports the
following eDP features:

- Alternate Scrambler Seed Reset (ASSR)Note: Offset
0x08Cbit-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.
