1 Switching is done on a lane-by-lane basis, but input equalization, output pre-emphasis, and loopback are set for each port.

PORT C REVERSE (CROSSOVER) CAPABILITY
Port C has a reversible I/O capability. The sense (input vs.
output) of the Port C pins can be swapped by toggling the
REVERSE_C control pin. This feature has been added to
facilitate the connection to different ASICs that may have
the opposite pinouts.
Figure 37 illustrates the reversible I/O function of Port C, and
Table 5 describes this function in a selection table that
corresponds to a TQFP-100 package. Please note that the
reverse capability is supported only on Port C.
