(2) Serial interface SIO3n
Serial interface SIO3n has one mode: 3-wire serial I/O mode.
3-wire serial I/O mode (fixed as MSB first)
This is an 8-bit data transfer mode using three lines: a serial clock line (SCK3n), serial output line (SO3n),
and serial input line (SI3n).
Since simultaneous transmit and receive operations are enabled in the 3-wire serial I/O mode, the
processing time for data transfer is reduced.
The first bit in 8-bit data in the serial transfer is fixed as MSB.
The 3-wire serial I/O mode is useful for connection to peripheral I/O devices, and display controllers, etc.,
that include a clocked serial interface.
