Using the receive line monitor mode and the hardware tristate function of transmit lines
XL1/2, the FALC56 now supports applications connecting two devices to one receive
and transmission line. In these kind of applications both devices are working in parallel
for redundancy purpose (see
one must be switched into transmit line tristate mode. If both channels are configured
identically and supplied with the same system data and clocks, the transmit path can be
switched from one channel to the other without causing a synchronization loss at the
remote end.
