**5595       Pentium PCI System I/O                          <12/24/97
***Notes:...
***Info:
SiS5595  is a  highly integrated  system I/O  that constitutes  a high
performance, rich featured, yet glueless solution for both Pentium and
Pentium  II  systems.   

The SiS5595 PCI  system I/O integrates the PCI-to-ISA  bridge with the
DDMA and PC/PCI  DMA, Serial IRQ capability, the  ACPI/Legacy PMU, the
Data  Acquisition   Interface,  the  Universal   Serial  Bus  host/hub
interface,  and the  ISA bus  interface,  which contains  the ISA  bus
controller, the  DMA controllers,  the interrupt controllers,  and the
Timers.  It also integrates the Keyboard controller, and the Real Time
Clock (RTC).  The built-in USB controller, which is fully compliant to
OHCI (Open Host Controller  Interface), provides two USB ports capable
of running full/low speed  USB devices. The Data Acquisition Interface
offers  the  ability of  monitoring  and  reporting the  environmental
condition  of the  PC.  It  could monitor  5  positive analog  voltage
inputs, 2  Fan speed inputs,  and one external temperature  inputs. It
also integrates the automatic power control logic to control the power
ON/OFF for ATX power supply.  In addition, SiS5595 also integrates the
thermal  detection and frequency  ratio control  logic for  Pentium II
CPU.
