13.1 Overview
13.1.1 Features
13.1.2 Configuration
This LSI includes 1 channel of UART (Universal Asynchronous Receiver Transmitter) which is an asynchronous serial
interface.
For the input clock, see Chapter 6, “Clock Generation Circuit”.
The use of UART requires setting of the secondary functions of Port 4. For the secondary functions of Port 4, see
Chapter 17, “Port 4”.
Figure 13-1 shows the configuration of the UART.
UART
• 5-bit/6-bit/7-bit/8-bit data length selectable.
• Odd parity, even parity, or no parity selectable.
• 1 stop bit or 2 stop bits selectable.
• Provided with parity error flag, overrun error flag, framing error flag, and transmit buffer status flag.
• Positive logic or negative logic selectable as communication logic.
• LSB first or MSB first selectable as a communication direction.
• Communication speed: Settable within the range of 200bps to 38400bps.
• Built-in baud rate generator.
