UART Interface
Overview
Universal Asynchronous Receiver Transmitter
Standard 16550 compatible UART interface
Min 9600Baud, Max 1.5MBaud
UART_TX and UART_RX used to transmit data
UART_CTS and UART_RTS used to implement RS232 hardware flow control
The UART (Universal Asynchronous Receiver Transmitter) provides a simple mechanism to communicate with other devices. The UART uses 4 (or 2 if HW – Handshake is not in use)) lines for serial data transmission.
