(2) 3-wire serial I/O mode
In this mode, the master device starts transfer by making the serial clock active and transfers 1-byte data in
synchronization with this clock.
This mode is used to communicate with a device having a conventional clocked serial interface. Basically,
communication is established by using three lines: serial clocks (SCK1 and SCK2), serial data inputs (SI1 and
SI2), and serial data outputs (SO1 and SO2). To connect two or more devices, a handshake line is
necessary.
