13.1.2
This LSI includes one channel of the 8/16-bit synchronous serial port (SSIO) and can also be used to control the device
incorporated with the SPI interface by using one GPIO as the chip enable pin.
For the input clock, see Chapter 6, “Clock Generation Circuit”.
When the synchronous serial port is used, the tertiary functions of port 4 must be set. For the tertiary functions of port 4,
see Chapter 21, “Port 4”.
Figure 13-1 shows the configuration of the synchronous serial port.
