Note 1: The operation error flag (TXERR and RXERR) are not automatically cleared by stopping transfer with SIOCR1<SIOS>
Note 2: *: Don't care
Note 1: SIOTDB is write only register. A bit manipulation should not be performed on the transmit buffer register using a read-
Note 2: The SIOTDB should be written after checking SIOSR<TXF> "1". When SIOSR<TXF> is "0", the writing data can't be
