(2) 3-wire serial I/O mode
This mode is to start transmission when the master device makes a serial clock active and to communicate
1-byte data in synchronization with this clock.
The interface in this mode communicates with devices that have conventional clocked serial interface.
Basically, communication is performed by using three lines: serial clock (SCK) and two serial data (SI and
SO) lines. To connect two or more devices, a handshake line is necessary.
