***Info:...
***Versions:...
***Features:
o   VL to PCI Bridge
    - Combined with VT82C486 or VT82C496G for 80486SX/DX/DX2/DX4 based 
      PCI/VL/ISA Green-PC systems
    - Combined with VT82C530MV chip set for Pentium/P54C/M1 based 
      PCI/VL/ISA Green-PC Systems
o   Sophisticated Bridging Capabilities
    - Supports PCI master to PCI slave cycles
    - Supports PCI master to VL bus slave, system memory and ISA 
      slave cycles
    - Supports VL master including CPU to PCI slave cycles
    - Supports ISA master to VL or PCI slave cycles
    - Supports multiple accelerated decoding schemes from VL master 
      including CPU to PCI and ISA slaves
    - Supports CPUs with write-back level-one cache
    - Concurrent CPU and PCI operation
    - 4 level of CPU/VL to PCI post write buffers
    - Automatic detection of data streaming burst cycles from CPU/VL 
      to PCI bus

      system memory and ISA slaves
    - 4 level of prefetch buffers from system memory for access by PCI 
      masters
    - Bursting capability for both PCI and CPU/VL bus
o   Intelligent PCI Interface
    - PCI 2.0 compliant
    - Synchronous or divide-by-two CPU clock
    - Hidden arbitration for up to four PCI masters
