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 was added to facilitate
the connection to different ASICs that may have the opposite
pinouts.
Figure 35 illustrates the reversible I/O function of Port C, and
Table 8 describes this function in a selection table that corresponds
to a TQFP-100 package. Note that the reverse capability is
supported only on Port C.
