Features and Overview

  • Asynchronous receiver and transmitter
  • Data-format compliant with RS-232 serial-data format
  • Burst rates up to 6 Mbits/second
  • Data framing consists of start, optional parity, and stop bits
  • Optional interrupt on receive register full and/or transmit buffer empty
  • Parity, overrun, and framing error detection
  • High level transmit and receive functions

The UART User Module is an 8-bit Universal Asynchronous Receiver Transmitter that supports duplex RS-232-compliant, data format serial communications over two wires. Received and transmitted data format includes a start bit, optional parity, and a stop bit. Programmable clocking and selectable interrupt or polling style operation is supported. Application Programming Interface (API) firmware routines are given to initialize, configure, and operate the UART. An additional high level API is also given to support background command receiving and string printing.
