1. Whether a framing error or parity error
has occurred that is to be read from
SCFRDR2 can be ascertained from
the FER and PER bits in SCFSR2.
2. When a break signal is received,
receive data is not transferred to
SCFRDR2 while the BRK flag is set.
However, note that the last data in
SCFRDR2 is H'00 (the break data in
which a framing error occurred is
stored).
