Real Time Clock with 256 byte extended CMOS. In addition to the standard ISA RTC
functionality, the integrated RTC also includes the date alarm, century field, and
other enhancements for compatibility with the ACPI standard. Notebook-class power
management functionality compliant with ACPI and legacy APM requirements.
Multiple sleep states (power-on suspend, suspend-to-DRAM, and suspend-to-Disk)
are supported with hardware automatic wake-up. Additional functionality includes
event monitoring, CPU clock throttling and stop (Intel processor protocol), PCI bus
clock stop control, modular power, clock and leakage control, hardware-based and
software-based event handling, general purpose I/O, chip select and external SMI.

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.

Internal I/O APIC (Advanced Programmable Interrupt Controller)
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 PCI-2.2 specification, the VT82C686B 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.
