Four-Host PCI-to-USB OpenHCI Host Controller
USS-344
QuadraBus
Power Management Interface
(continued)
The CLK48STOP output pin is active if all four PCI cores in the USS-344 multifunction PCI device have been
placed into the D3
hot
state. This will allow the external 48 MHz oscillator to be disabled and in a low-power mode
while in this state. CLK48STOP is only active in D3
hot
state since this is the only low-power state with sufficient
state-change latency to allow the external oscillator to be stopped.
PMEN is an open collector output allowing wire-OR of several PMEN signals.
The following Power Management register definitions present the specific implementation of the
PCI Bus Power
Management Interface Specification
for the USS-344. All the following registers are located in the PCI configura-
tion memory space of each controller in the USS-344. All further information concerning the register functions and
the system implementation of this interface should be referenced from the
PCI Bus Power Management Interface
Specification Revision 1.1
available from the PCI Special Interest Group.
