the
USE_8B_10B_MODE parameter to
OFF, the rx_errdetect port is not
available.
rx_disperr[]
No Indicates whether the
8B/10B decoder
detects a disparity
error.
Output port [NUMBER_OF_CHANNELS *
DWIDTH_FACTOR - 1..0] wide.
rx_signaldetect[]
No Indicates whether there
is a legal voltage level
on the input buffer.
Output port [NUMBER_OF_CHANNELS -
1..0] wide. This port is available only if the
PROTOCOL parameter is set to XAUI or
GigE. This signal is always set in the
modes in which it is enabled. It is still
enabled even after the signal is a forced

USE_SELF_TEST_MODE parameter is
turned on.
