Overview

he D16550 is a soft Core of Universal Asynchronous Receiver/Transmitter (UART), functionally identical to the TL16C550A. It allows serial transmission in two modes - UART and FIFO. In the FIFO mode, internal FIFOs are activated, allowing 16 bytes (plus 3 bits of error data per byte in the RCVR FIFO) to be stored in both, receive and transmit directions. The D16550 performs serial-to-parallel conversion on data characters, received from a peripheral device or a MODEM and parallel-to-serial conversion on data characters, received from the CPU. The CPU can read a complete status of the UART at any time, during the functional operation. Reported status information includes the type and condition of transfer operations performed by the UART, as well as any error conditions (parity, overrun, framing or break interrupt).

Features

  • Software compatible with 16450 and 16550 UARTs; Configuration capability; Separate configurable BAUD clock line
  • Majority Voting Logic; Supports RS232 and RS485 standards; Two modes of operation: UART mode and FIFO mode
  • Adds or deletes standard asynchronous communication bits (start, stop and parity) to or from the serial data
  • Independently controlled transmit, receive, line status and data set interrupts; False start bit detection
  • 16 bit programmable baud generator; Independent receiver clock input; MODEM control functions (CTS, RTS, DSR, DTR, RI, and DCD)
