New Revision: 7052

Log:
There appears to be an undocumented errata where the qfalc v3.1 with regards
to CAS robbed bit signalling configuration.  For some reason, it checks the
config of the port configuration registers in addition to the ones that
specify where the robbied bit signalling transmit will come from.  For our
case, we want it to come from the transmit register block.  This new port
configuration allows v3.1 to continue to use the register block as expected
instead of from an external serial pin.
