  1. These ports are applicable for Legacy GT Wizard only.
  2. You can control the gtwiz_reset_all_in based on the configuration and the number of Quads individually. For example, for NRZ configurations, each quad can be controlled by each bit of reset input. For PAM4, each dual can be controlled by each bit. The operation of reset should be based on the configuration selected, similar to the Assertion and Deassertion of DCMAC Resets section.
  3. For more information on the usage of the above mentioned GT reset control ports, see the Validating the Example Design section.
