VT82C686A
The VT82C686A also enhances the functionality of the standard ISA peripherals. The integrated interrupt controller supports both
edge and level triggered interrupts channel by channel. The integrated DMA controller supports type F DMA in addition to
standard ISA DMA modes. Compliant with the PCI-2.2 specification, the VT82C686A supports delayed transactions and remote
power management so that slower ISA peripherals do not block the traffic of the PCI bus. Special circuitry is built in to allow
concurrent operation without causing dead lock even in a PCI-to-PCI bridge environment. The chip also includes eight levels
(doublewords) of line buffers from the PCI bus to the ISA bus to further enhance overall system performance.
