XR17C158
PCI BUS OCTAL UART
SEPTEMBER 2001
REV. 1.1.3
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 program-
mable transmit and receive FIFO level triggers, trans-
mit and receive FIFO level counters, automatic RTS/
CTS or DTR/DSR hardware flow control with pro-
grammable hysteresis, automatic software (Xon/Xoff)
flow control, IrDA (Infrared Data Association) encod-
er/decoder, 8 multi-purpose definable inputs/outputs,
and a 16-bit general purpose timer/counter.
