and the data is received in synchronization with the falling edge of the clock.
When SIOCR<SIOEDG> is "1", the data is transmitted in synchronization with the rising edge of the clock
Note:When an external clock input is used, 4/fcgck or longer is needed between the receive edge at the 8th
bit and the transfer edge at the first bit of the next transfer.
