Description

The XR16L784CV (784) is a quad Universal Asynchronous Receiver and Transmitter (UART). The device is designed for high bandwidth requirement in communication systems. The global interrupt source register provides a complete interrupt status indication for all 4 channels to speed up interrupt parsing. Each XR16L784CV has its own 16C550 compatible set of configuration registers, transmit and receive FIFOs of 64 bytes, fully programmable transmit and receive FIFO level triggers, transmit and receive FIFO level counters, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, automatic software (Xon/Xoff) flow control, IrDA (Infrared Data Association)  ncoder/decoder, and a 16-bit general purpose timer/counter.
