7)
Two 16550-compatible serial I/O ports with infrared communications
port option. A third serial port is available to be dedicated to the IR
interface.
8)
Integrated PCI-mastering dual full-duplex direct-sound AC97-link-
compatible sound system. Hardware soundblaster-pro and hardware-
assisted FM blocks are included for Windows DOS box and real-mode
DOS compatibility. Loopback capability is also implemented for
directing mixed audio streams into USB and 1394 speakers for high
quality digital audio
9)
Two game ports and One MIDI port
10)
ECP/EPP-capable parallel port
11)
Standard floppy disk drive interface
12)
Distributed DMA capability for support O ISA legacy DMA over
the PCI bus. Serial IRQ is also supported for docking and non-docking
application.
13)
Plug and Play controller that allows complete steerability of all PCI
interrupts and internal interrupts/ DMA channels to any interrupt
channel. One additional steerable interrupt channel is provided to allow
plug and play and reconfigurability of onboard peripherals for Windows
family compliance.
The VT82C686B 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 PCI2.2 specification, the VT83C686A 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.
