Description
Data input from the hard receiver.
Clock input from the hard receiver.
Data output for the hard transmitter.
Control signal to indicate the control word in
tx_parallel_data_in signal.
Clock input from the hard transmitter.
Control signal to indicate that control word is
detected in the hard transceiver.
Pattern detect output for the hard transceiver.
Disparity error output for the hard transceiver.
Polarity inversion input for the hard transceiver.
Some transceiver signals are removed due to the exclusion of hard transceiver in this
configuration. Refer to the next section for a more detailed description of the signals.
Signals
Table 4–5 through Table 4–10 show the SerialLite II MegaCore function signals.

The signals required for a given configuration, as well as the appropriate bus widths,
are created automatically by the SerialLite II parameter editor based upon the
parameter values you select.
Table 4–5 shows the high-speed serial interface signals.
