23. Clock Synchronous Serial Interface
The clock synchronous serial interface is configured as follows.
Clock synchronous serial interface
The clock synchronous serial interface uses the registers at addresses 0193h to 019Dh. Registers, bits, symbols, and
functions vary even for the same addresses depending on the mode. Refer to the registers of each function for details.
Also, the differences between clock synchronous communication mode and clock synchronous serial mode are the
options of the transfer clock, clock output format, and data output format.
