range will not be claimed by the bridge. The I/O window for the XIO2001 has a minimum size of 4
KBytes and is naturally 4K-aligned. Typically, most systems use only 16-bit addressing for I/O
transactions, so the upper base and limit registers remain 0.
limit registers, the bridge must be programmed with a memory address window containing the
nonprefetchable memory resources of all downstream PCI devices requiring nonprefetchable memory.
Memory windows have a minimum size of 1 MByte and are naturally 1M-aligned. The bridge does not
claim either a memory transaction initiated from upstream that does not fall within its memory window
nor memory transactions initiated downstream that do fall within its memory window.
prefetchable limit upper 32-bit registers – PCI offsets 0x24, 0x26, 0x28, and 0×2C: Identical to the
memory base and limit registers but for prefetchable memory resources. The prefetchable base upper
32-bit, and prefetchable limit upper 32-bit registers are only used if 64-bit addressing is in use and in
most systems both of these registers will remain all zeroes. If 64-bit addressing is desired and the
memory window for devices behind the XIO2001 resides all or in part in 64-bit memory space then the
prefetchable base upper 32-bit register will combine with the prefetchable base register and the
prefetchable limit upper 32-bit register will combine with the prefetchable limit register to create 64-bit
base and limit registers. All memory addresses between the two addresses will be considered to be
located behind the bridge.
base register will be considered invalid. In this situation the bridge will react as if all resources of that
type resided upstream of the bridge. The bridge will respond to all downstream transactions of that
type with Unsupported Request and will claim and forward upstream any transactions of that type that
initiate on the PCI bus.
4.4.4Check Devices Downstream From Bridge
Once the bridge is communicating and is properly configured, check if devices downstream from the
bridge have been configured as required. Check the Windows Device Manager to determine if the device
drivers have been loaded or if other problems exist with the device. Once you have performed these
checks, you can perform PCI transactions on the bus and examine them with any standard PCI analyzer.

REGULATORY COMPLIANCE INFORMATION
As noted in the EVM User’s Guide and/or EVM itself, this EVM and/or accompanying hardware may or may not be subject to the Federal
Communications Commission (FCC) and Industry Canada (IC) rules.
For EVMs not subject to the above rules, this evaluation board/kit/module is intended for use for ENGINEERING DEVELOPMENT,
DEMONSTRATION OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end product fit for general consumer
use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing
devices pursuant to part 15 of FCC or ICES-003 rules, which are designed to provide reasonable protection against radio frequency
interference. Operation of the equipment may cause interference with radio communications, in which case the user at his own expense will
be required to take whatever measures may be required to correct this interference.
General Statement for EVMs including a radio
User Power/Frequency Use Obligations: This radio is intended for development/professional use only in legally allocated frequency and
power limits. Any use of radio frequencies and/or power availability of this EVM and its development application(s) must comply with local
laws governing radio spectrum allocation and power limits for this evaluation module. It is the user’s sole responsibility to only operate this

FCC Interference Statement for Class B EVM devices
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
For EVMs annotated as IC – INDUSTRY CANADA Compliant
This Class A or B digital apparatus complies with Canadian ICES-003.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the
equipment.
Concerning EVMs including radio transmitters
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this
device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired
operation of the device.
Concerning EVMs including detachable antennas
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
This radio transmitter has been approved by Industry Canada to operate with the antenna types listed in the user guide with the maximum
permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain
greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
Cet appareil numérique de la classe A ou B est conforme à la norme NMB-003 du Canada.
Les changements ou les modifications pas expressément approuvés par la partie responsable de la conformité ont pu vider l’autorité de
l'utilisateur pour actionner l'équipement.
Concernant les EVMs avec appareils radio
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est
autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout
brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.
Concernant les EVMs avec antennes détachables
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain
maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à
l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente
(p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le manuel
