[2] When a break signal is received,
has occurred in the receive data that
is to be read from SCFRDR can be
ascertained from the FER and PER
bits in SCFSR.
receive data is not transferred to
SCFRDR while the BRK flag is set.
However, note that the last data in
SCFRDR is H'00, and the break data
in which a framing error occurred is
stored.
