4.3.6 PCI Interface

The Intel

C602 chipset PCI interface provides a 33 MHz, Revision 2.3 implementation. The

C602 chipset integrates a PCI arbiter that supports up to four external PCI bus masters in

addition to the internal Intel

C602 chipset requests. This allows for combinations of up to four

PCI down devices and PCI slots.

4.3.7 Low Pin Count (LPC) Interface

The Intel

C602 chipset implements an LPC Interface as described in the LPC 1.1 Specification.

The Low Pin Count (LPC) bridge function of the Intel

C602 resides in PCI Device 31: Function

0. In addition to the LPC bridge interface function, D31:F0 contains other functional units

including DMA, interrupt controllers, timers, power management, system management, GPIO,

and RTC.

4.3.8 Serial Peripheral Interface (SPI)

The Intel

C602 chipset implements an SPI Interface as an alternative interface for the BIOS

flash device. The SPI flash is required to support Gigabit Ethernet and Intel

Active

Management Technology. The Intel

C602 chipset supports up to two SPI flash devices with

speeds up to 50 MHz.

4.3.9 Compatibility Modules (DMA Controller, Timer/Counters, Interrupt Controller)

The DMA controller incorporates the logic of two 82C37 DMA controllers, with seven

independently programmable channels. The Intel

C602 chipset supports LPC DMA through the

Intel

C602 chipset’s DMA controller.

The timer/counter block contains three counters that are equivalent in function to those found in

one 82C54 programmable interval timer. These three counters are combined to provide the

system timer function, and speaker tone.

The Intel

C602 chipset provides an ISA-Compatible Programmable Interrupt Controller (PIC)

that incorporates the functionality of two 82C59 interrupt controllers. In addition, the Intel

C602

chipset supports a serial interrupt scheme.

All of the registers in these modules can be read and restored. This is required to save and

restore system state after power has been removed and restored to the platform.

4.3.10 Advanced Programmable Interrupt Controller (APIC)

In addition to the standard ISA compatible Programmable Interrupt controller (PIC) described in

the previous section, the Intel

C602 chipset incorporates the Advanced Programmable

Interrupt Controller (APIC).

4.3.11 Universal Serial Bus (USB) Controllers

The Intel

C602 chipset has up to two Enhanced Host Controller Interface (EHCI) host

controllers that support USB high-speed signaling. High-speed USB 2.0 allows data transfers up

to 480 Mb/s which is 40 times faster than full-speed USB. The Intel

C602 chipset supports up

to fourteen USB 2.0 ports. All fourteen ports are high-speed, full-speed, and low-speed capable.
