PORT2
indicates that an input channel is bypassed to an output channel
ST-BUS Mode 3 supports connection to 2B+D devices where timeslots 0 and 1 transport D and C channels and both
echo canceller I/O channels are assigned to ST-BUS timeslots 2 and 3. Both PORT1 and PORT2 must be configured in
ST-BUS Mode 3.

ST-BUS Mode 4 allows 16 bits 2’s complement linear data to be transferred using ST-BUS I/O timing. Note that PORT1
and PORT2 need not necessarily both be in mode 4.
