This section describes reset sequences for transceiver channels in bonded and
non-bonded configurations. Timing diagrams of some typical configurations are
shown to facilitate proper reset sequence implementation. In these functional modes,
you can set the receiver CDR either in automatic lock or manual lock mode.
In manual lock mode, the receiver CDR locks to the reference clock (lock-to-reference)
or the incoming serial data (lock-to-data), depending on the logic levels on the
rx_locktorefclk and rx_locktodata signals. With the receiver CDR in manual lock
mode, you can either configure the transceiver channels in the Stratix IV device in a
non-bonded configuration or a bonded configuration. In a bonded configuration, for
example in XAUI mode, four channels are bonded together.

modes for the rx_locktorefclk and rx_locktodata signals.
Table 4–4. Lock-To-Reference and Lock-To-Data Modes
Bonded Channel Configuration
In a bonded channel configuration, you can reset all the bonded channels
simultaneously. Examples of bonded channel configurations are XAUI, PCIe, and
Basic ×4 functional modes. In Basic ×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 output status signals, rx_pll_locked and
rx_freqlocked. You must consider the timing of these signals in the reset sequence.
