12 Synchronous Serial Port
12.1 Overview
12.1.1 Features
12.1.2 Configuration
This LSI includes two channels of 8/16-bit synchronous serial ports (SSIO). It can also be used to control the device
incorporated with the SPI interface by using one GPIO as the chip enable pin.
When the synchronous serial port is used, the tertiary functions of Port 4 or the tertiary functions of Port 5 must be set.
For the tertiary function setting of Port 4, see Chapter 17, "Port 4." For the tertiary function setting of Port 5, see Chapter
18, "Port 5."
Figure 12-1 shows the configuration of the synchronous serial port.
• Master or slave selectable
• MSB first or LSB first selectable
• 8-bit length or 16-bit length selectable fro the data length
