Only PCI-to-PCI bridge responce to this type and if it match its local bus number, the bridge convert it to TYPE0, otherwise pass it throw. Only devices on a local bus responce to this type.īits AD 31:2 value are much like the. There are two types of configuration register transactions:ĪD7:2 signals used for up to 64 DW of configuration registers.ĪD10:9 signals used for up to 8 functions in one PCI device.ĪD31:11 signals are don't care thefroe can be use to distinguish IDSEL on each device. IDSEL is Initialization Device Select and used as a chip select during configuration transactions. Offset interpret to AD31:11 signals and each connected to device IDSEL pin.Īlthough theoretically max of 32 (2^5) devices, with this method only 21 (AD11 to AD31) can actually be connected on a local bus. The following could be an example mapping. As an example of this, assume that there is a motherboard with 5 possible devices. Since there are 32 possible devices per bus, this works out nicely. The one bit of the address/data bus will be brought in as the IDSEL for a particular endpoint. When a configuration is taking place, the address line will assert a one hot address such as 0x00000010. This is seen in the picture below:Īdditionally, it seems that in practice, it is common to tie these IDSEL lines to a one hot mapping from the 32 bit address/data bus. If for example a motherboard has two PCI endpoint slots, there will be two discrete IDSEL lines from the CPU to the endpoints. In terms of determining the actual device number, this is done by the host hardware. During configuration transactions, the IDSEL is used to indicate to a PCI endpoint (or bridge) that it is currently selected.

The device is determined by a hardware line IDSEL that is an input to every PCI endpoint.
