SIOSR<RXF> is “1” in an external clock operation. If receive error occurs, set the
SIOCR1<SIOS> to “0” for reading the data that received immediately before error occur-
rence. And read the data from SIORDB. Data in shift register (at errors occur) can be
read by reading the SIORDB again.
SIOSR<RXF> is cleared to “0”. After clearing SIOCR1<SIOS> to “0”, when 8-bit seri-
