GENERAL DESCRIPTION

The XR16M598

Universal Asynchronous Receiver and Transmitter

(UART). The highly integrated device is designed for

high

systems.

provides a complete interrupt status indication for all

8 channels to speed up interrupt parsing. Each UART

has its own 16C550 compatible set of configuration

registers, TX and RX FIFOs of 16 bytes, fully

programmable transmit and receive FIFO trigger

levels, automatic RTS/CTS or DTR/DSR hardware

flow control with programmable hysteresis, automatic

software (Xon/Xoff) flow control, RS-485 half-duplex

direction control with programmable turn-around

delay, Intel or Motorola bus interface and sleep mode

with a wake-up indicator.
