9.3.6. Load a PMA Configuration

This command selects internal serial loopback, PRBS31, and loads a PMA configuration. This example, detailed below, enables a low effort initial adaptation (any effort level is acceptable). This PMA adaptation needs to be run in order to load the PMA configuration. PRBS and loopback modes are set after PMA adaptation is complete.
  1. Load a PMA configuration to the current channel on the E-tile:
    1. Write 0x200[7:0] = 8'hD0.
    2. Write 0x201[7:0] = 8'h02.
    3. Write 0x202[7:0] = 8'h01.
    4. Write 0x203[7:0] = 8'h96.
  2. Read 0x207 until it becomes 0x80. This indicates that the operation completed successfully.
