Motherboard Description
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 on-board peripherals for Windows family
compliance.
The VT8233CE 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 VT8233CE 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.
1-10 I/O INTERFACE CONTROLLER
The motherboard uses the ITE 8705 LPC Super-I/O controller which
features:
Supports 2 serial ports, IR port, parallel port, and floppy disk
controller functions
Two UARTs for Complete Serial Ports
Even, odd, stick or no parity bit generation and detection
Programmable baud rate generator
High speed baud rate (230Kbps, 460Kbps) support
Independent transmit/receiver FIFOs
Modem Control
Plug and play with 96 base IO address and 12 IRQ options
One dedicated IR port
Third serial port dedicated to IR function
IR function either through the two complete serial ports or the
third dedicated port
