REV. 1.2.2
The XR17D1581 (D158) is an octal PCI Bus Universal Asynchronous Receiver and Transmitter (UART) with support for PCI Bus universal VIO buffers in the same package and pin-out as the XR17C158, XR17C154 and XR17D154. The device is designed to meet the 32-bit PCI Bus and high bandwidth requirement in communication systems. A global interrupt source register provides a complete interrupt status indication for all 8 channels to speed up interrupt parsing. Each UART has its own 16C550 com.
