Each UART supports:
• Full-duplex operation
• Software-programmable baud generators
• Software-selectable serial interface data format, that includes:
• Data length
• Parity
• 1/1.5/2 STOP bit
• Baud rate
• Overrun, parity, and framing error detection
The UART ports are routed to 3PIN connectors, as shown in the image below.
