8.1.2
PCI Initiator/Target
A PCI initiator initiates PCI transactions to the PCI bus; a PCI target responds to PCI
transactions as a slave. In the case of the ISP1561, the two Open Host Controllers
and the Enhanced Host Controller function as both initiators or the targets of PCI
transactions issued by the host CPU.
All USB Host Controllers have their own operational registers, which can be accessed
by the system driver software. Drivers use these registers to configure the Host
Controller hardware system, issue commands to it and/or monitor the status of the
current hardware operation. The Host Controller plays the role of a PCI target. All
operational registers of the Host Controllers are PCI transaction targets of the CPU.
Normal USB transfers require the Host Controller to access system memory fields,
which are allocated by USB Host Controller Drivers (HCDs) and PCI drivers. The
Host Controller hardware interacts with the HCD by accessing these buffers. The
Host Controller works as an initiator in this case, and becomes a PCI master.
8.2 PCI configuration registers
The OHCI USB Host Controllers and EHCI USB Host Controller contain two sets of
software-accessible hardware registers
:
PCI configuration registers and
memory-mapped Host Controller registers.
A set of the configuration registers are implemented for each of the three PCI
functions of the ISP1561, see
Table 3
.
Remark:
In addition to the normal PCI header (from offset index 00H to 3FH),
implementation-specific registers are defined to support power management and
function-specific features.
