| 0x080 | R/W | TRANSMITTER_ENABLE. Enables the basic operations of the
transmitter. [0] - When set to 1, stream transmission is enabled. When set to 0, all lanes of the main link output stuffing symbols. |
| 0x084 | R/W | MAIN_STREAM_ENABLE. Enables the transmission of main link video
information. [0] - When set to 0, the active lanes of the DisplayPort transmitter outputs only VB-ID information with the NoVideo flag set to 1. Note: Main stream enable or disable functionality is gated by the VSYNC
input. The values written in the register are applied at the video frame boundary
only.

| 0x0C0 | WO | FORCE_SCRAMBLER_RESET. Reads from this register always return
0x0. [0] - 1 forces a scrambler reset. |
| 0x0D0 | R/W | TX_MST_CONFIG: MST Configuration. [0] – MST Enable: Set to 1 to enable MST functionality. [1] – VC Payload Updated in sink: This is an WO bit. Set to 1 after reading DPCD register 0x2C0 (bit 0) is set. |

BRIDGE_STATUS. Reports the values of various status bits from the "AXI4-Stream to Video Bridge IP" in an AXI4-Stream mode. This register contents are invalid in the Native mode. [0] - Bridge lock. Value '1' indicates that the video timing parameter programmed to Video Timing Controller (VTC) matches the video on AXI4-Stream interface. Value '0' indicates wrong video timing and hence, core's correct functionality is not guaranteed. [1] - Bridge overflow. Value '1' indicates that there is an overflow inside the "AXI4-Stream to Video Bridge IP" and hence, correct functionality is not guaranteed. [2] - Bridge underflow. Value '1' indicates that there is an underflow inside the "AXI4-Stream to Video Bridge IP" and hence, correct functionality is not guaranteed. [3] - Bridge lock stream-2 [4] - Bridge overflow stream-2 [5] - Bridge underflow stream-2 [6] - Bridge lock stream-3 [7] - Bridge overflow stream-3 [8] - Bridge underflow stream-3 [9] - Bridge lock stream-4 [10] - Bridge overflow stream-4 [11] - Bridge underflow stream-4 |
