the transfer is stopped (when SIOSR<SIOF>= “0”)
Transfer data direction can be selected by using SIOCR1<SIODIR>. The transfer data direction can't be set
When the data direction is changed, the writing instruction to SIOCR1<SIODIR> should be executed while

MSB transmit mode
MSB transmit mode is selected by setting SIOCR1<SIODIR> to “0”, in which case the data is
LSB transmit mode
LSB transmit mode is selected by setting SIOCR1<SIODIR> to “1”, in which case the data is
MSB receive mode
MSB receive mode is selected by setting SIOCR1<SIODIR> to “0”, in which case the data is
