7.7.2 Clocked serial interface (CSI)
In this mode, the master device starts transfer by making the serial clock active and transfers 1-byte data in
synchronization with this clock.
(1) 3-wire serial I/O mode
This mode is to communicate with devices having a conventional clocked serial interface.
Basically, communication is established in this mode with three lines: serial clock (SCK0) serial data input
(SI0), and serial data output (SO0) lines.
Generally, a handshake line is necessary to check the reception status.
