Section 14 Serial Communication Interface with FIFO (SCIF)
14.3.7
SCFSR is a 16-bit register. The upper 8 bits indicate the number of receives errors in the SCFRDR
data, and the lower 8 bits indicate the status flag indicating SCIF operating state.
The CPU can always read and write to SCFSR, but cannot write 1 to the status flags (ER, TEND,
TDFE, BRK, RDF, and DR). These flags can be cleared to 0 only if they have first been read
(after being set to 1). Bits 3 (FER) and 2 (PER) are read-only bits that cannot be written. SCFSR is
initialized to H'0060 by a power-on reset.

Description
Number of Parity Errors
Indicate the number of data including a parity error in
the receive data stored in the receive FIFO data
register (SCFRDR). The value indicated by bits 15 to
12 represents the number of parity errors in
SCFRDR. When parity errors have occurred in all 16-
byte receive data in SCFRDR, PER3 to PER0 show
0.
Number of Framing Errors
Indicate the number of data including a framing error
in the receive data stored in SCFRDR. The value
indicated by bits 11 to 8 represents the number of
framing errors in SCFRDR. When framing errors have
occurred in all 16-byte receive data in SCFRDR,
FER3 to FER0 show 0.
