1394a PCI PHY/Link Open Host Controller

FW322 Functional Description

The FW322 is comprised of four major functional sections (see Figure 1): PCI core, OHCI isochronous and

asynchronous data transfer, link core, and PHY core. The following is a general description of each of the major

sections.

PCI Core

The PCI core (shown in Figure 2) serves as the interface to the PCI bus. It contains the state machines that allow

the FW322 to respond properly when it is the target of the transaction. Also, during 1394 packet transmission or

reception, the PCI core arbitrates for the PCI bus and enables the FW322 to become the bus master for reading the

different buffer descriptors and management of the actual data transfers to/from host system memory.

The PCI core also supports the PCI Bus Power Management Interface Specification v.1.1. Included in this support

is a standard power management register interface accessible through the PCI configuration space. Through this

register interface, software is able to transition the FW322 into four distinct power consumption states (D0, D1, D2,

and D3hot). This permits software to selectively increase/decrease the power consumption of the FW322 for

reasons such as periods of system inactivity or power conservation. In addition, the FW322 also includes support

for waking up the system through the generation of a power

management event (PME).

The FW322 supports generation of a power management event (PME) while in the D0, D1, D2, and D3hot power

states.
