(2) Three-wire serial I/O mode
In this mode, the master device makes the serial clock active to start transmission, then transfers 1-byte data
in phase with the clock.
This mode is designed for communication with a device incorporating a conventional synchronous serial interface.
Basically, three lines are used for communication: the serial clock line (SCK) and the two serial data lines (SI
and SO).
In general, a handshake line is required to check the state of communication.
