Section 15 Serial Communication Interface with FIFO (SCIF)
15.3.7
SCFSR is a 16-bit register. The upper 8 bits indicate the number of receive errors in the receive
FIFO data register, 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). The PER flag (bits 15 to 12 and bit 2) and the FER flag (bits 11 to 8 and bit
3) are read-only bits that cannot be written.

Number of Parity Errors
Description
Indicate the quantity 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 after the ER bit in SCFSR is set, represents the
number of parity errors in SCFRDR. When parity
errors have occurred in all 16-byte receive data in
SCFRDR, PER[3:0] shows 0000.
Number of Framing Errors
Indicate the quantity of data including a framing error
in the receive data stored in SCFRDR. The value
indicated by bits 11 to 8 after the ER bit in SCFSR is
set, represents the number of framing errors in
SCFRDR. When framing errors have occurred in all
16-byte receive data in SCFRDR, FER[3:0] shows
0000.
