3.8.7. Run-time Reset Sequence—RX

Figure 77. Run-time Reset Sequence—RX

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

  1. Assert rx_reset.
  2. rx_ready deasserts, indicating that the RX datapath is no longer operational.
  3. rx_reset_ack asserts, indicating that the RX datapath is fully in reset. You then deassert rx_reset to bring RX out of reset and rx_ready asserts.
