Bonded Channel Configuration
In a bonded channel configuration, you can reset all the bonded channels
simultaneously. Examples of bonded channel configurations are the XAUI, PCIe Gen1
×2 and ×4, and Basic ×2 and ×4 functional modes. In Basic ×2 and ×4 functional mode,
you can bond Transmitter Only channels together.
In XAUI mode, the receiver and transmitter channels are bonded. Each of the receiver
channels in this mode has its own rx_freqlocked output status signals. You must
consider the timing of these signals in the reset sequence.

Transmitter Only Channel
This configuration contains only a transmitter channel. If you create a Transmitter
Only instance in the ALTGX MegaWizard Plug-In Manager in Basic ×4 functional
mode, use the reset sequence shown in
