16.3.7
SCFSR is a 16-bit register. The lower 8 bits specify the status flags that indicate the SCIF
operating status. The upper 8 bits indicate the receive error number of data in the receive-FIFO
register.
SCFSR can be read or written to by the CPU at all times. However, 1 cannot be written to the ER,
TEND, TDFE, BRK, RDF, and DR flags. Also note that in order to clear these flags to 0, they
must be read as 1 beforehand.
The FER and PER flags are read-only flags and cannot be modified.
SCFSR is initialized to H'0060 by a power-on reset or manual reset. It is not initialized in standby
mode or in the module standby state, and retains its contents.

Description
Parity Error Number 3 to 0
Indicate the number of data bytes, in which parity
errors are generated, in receive data stored in
SCFRDR.
After setting the ER bit in SCFSR, the values of bits
15 to 12 indicate the number of parity error
generated data. When all 16 bytes of receive data
in SCFRDR has parity errors, the PER3 to PER0
bits indicate 0.
Framing Error Number 3 to 0
Indicate the number of data bytes, in which framing
errors are generated, in receive data stored in
SCFRDR.
After setting the ER bit in SCFSR, the values of bits
11 to 8 indicate the number of framing error
generated data.
When all 16 bytes of receive data in SCFRDR has
framing errors, the FER3 to FER0 bits indicate 0.
