The key features of the UART module are:
• Full-duplex, 8 or 9-bit data communication
• Even, Odd or No Parity options (for 8-bit data)
• One or two Stop bits
• Fully integrated Baud Rate Generator with 16-bit
• Baud rates range from 38 bps to 1.875 Mbps at a
• 4-word deep transmit data buffer
• 4-word deep receive data buffer
• Parity, Framing and Buffer Overrun error detection
• Support for Interrupt only on Address Detect
• Separate Transmit and Receive Interrupts
• Loopback mode for diagnostic support
