Figure 76. Run-time Reset Sequence—TX

The figure above illustrates the following run-time TX reset sequence:36

  1. Assert tx_reset.
  2. tx_ready deasserts, indicating that the TX datapath is no longer operational.
  3. tx_reset_ack asserts, indicating that the TX datapath is fully in reset. You then deassert tx_reset to bring TX out of reset and tx_ready asserts.
