The LPC2129/38 each contain two UARTs. In addition to standard transmit and receive data lines, the UART1 also provides a full modem control handshake interface.
Features
• 16 B Receive and Transmit FIFOs.
• Register locations conform to 16C550 industry standard.
• Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B.
• Built-in fractional baud rate generator covering wide range of baud rates without a need for external crystals of particular values.
• Transmission FIFO control enables implementation of software (XON/XOFF) flow control on both UARTs
• UART1 is equipped with standard modem interface signals. This module also provides full support for hardware flow control (auto-CTS/RTS).
