PRELIMINARY
XR17C158
PCI BUS OCTAL UART
MARCH 2000
REV. 1.0.1
GENERAL DESCRIPTION
The XR17C158
1
(158) is an octal Universal Asyn-
chronous Receiver and Transmitter (UART). The de-
vice is designed to meet the 32-bit PCI Bus and high
bandwidth requirement in communication systems.
The global interrupt source register provides a com-
plete interrupt status indication for all 8 channels to
speed up interrupt parsing. Each UART has its own
16C550 compatible set of configuration registers,
transmit and receive FIFOs of 64 bytes, fully pro-
grammable 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)
encoder/decoder, 8 multi-purpose definable inputs/
outputs, and a 16-bit general purpose timer/counter.
