Product data sheet
6.4.2 ACPI and power states
device setup without depending on the device driver, and support association of the
proper software driver. Some of the configuration information is hard-wired in the device;
some information is loaded during the system start-up.

The device vendor ID is hard coded to 1131h, which is the code for Philips as registered
with PCI-SIG.
The device ID is hard coded to 7130h.
During power-up, initiated by PCI reset, the SAA7130HL fetches additional system
information via the I
codes for the system vendor ID, sub-system ID (board version) and ACPI related
parameters into the configuration registers.
The PCI specification 2.2 requires support of Advanced Configuration and Power
Interface specification 1.0 (ACPI); more details are defined in the PCI Power Management
Specification 1.0 .
The power management capabilities and power states are reported in the extended
configuration space. The main purpose of ACPI and PCI power management is to tailor
the power consumption of the device to the actual needs.
The SAA7130HL supports all four ACPI device power states (see
The pin PROP_RST_N of the peripheral interface is switched active LOW during the PCI
reset procedure, and for the duration of the D3-hot state. Peripheral devices on board of
the add-on card should use the level of this signal PROP_RST_N to switch themselves in
any Power-save mode (e.g. disable device) and reset to default settings on the rising edge
of signal PROP_RST_N.
