Receiver and Transmitter Channel—Receiver CDR in Manual Lock Mode
This configuration contains both a transmitter and receiver channel. If you create a
Receiver and Transmitter instance in the ALTGX MegaWizard Plug-In Manager with
the receiver CDR in manual lock mode, use the reset sequence shown in
the rx_digitalreset signal (marker 8). At this point, the transmitter and
receiver are ready for data traffic.
