SCFSR is a 16-bit register that consists of status flags that indicate the operating status of the
SCIF.
SCFSR can be read from or written to by the CPU at all times. However, 1 cannot be written to
flags ER, TEND, TDFE, BRK, RDF, and DR. Also note that in order to clear these flags they
must be read as 1 beforehand. The FER flag and PER flag are read-only flags and cannot be
modified.
