DESCRIPTION
The Epic Ei16C550 Universal  Asynchronous Receiver Transmitter (UART) is a CMOS-VLSI communication device in a single package.
   
FEATURES
• 5V Operation
• Full duplex asynchronous receiver and transmitter
• Easily interfaces to most popular microprocessors
• Adds or deletes standard asynchronous
    communication bits (start, stop, and parity) to or
    from a serial data stream
• Independently controlled transmitter, receiver,
    line status, and data set interrupts
• Programmable baud rate generator allows
    division of any input clock by 1 to (216-1) and
    generates the internal 16 x clock
• Independent receiver clock input
• MODEM control functions (CTS, RTS, DSR,
    DTR, RI,and DCD)
• Fully programmable serial interface
    characteristics:
    - 5, 6, 7, or 8 bit characters
    - Even, odd, or no-parity bit generation and
        detection
    - 1, 1.5, or 2 stop bit generation
    - Baud generation (DC to 56k baud)
• False start bit detection
• Complete status reporting capabilities
• Tri-StateÆTTL drive capabilities for bidirectional data bus and control bus
• Line break generation and detection
• Internal diagnostic capabilities:
    - Loopback controls for communications link fault
        isolation
    - Break, parity overrun, and framing error simulation
• Fully prioritized interrupt systems controls
• 16 byte FIFO for reduced CPU overhead
