received data (H'00) to SCFRDR2 stops
after detection. When the break ends and
the receive signal becomes mark 1, the
transfer of the received data resumes. The
received data of a frame in which a break
signal is detected is transferred to
SCFRDR2. After this, however, no
received data is transferred until a break
ends with the received signal being mark 1
and the next data is received.
