17.4.2.11 Configuration Cycles
This section describes PCI configuration cycles used for configuring standard PCI devices. The PCI
configuration space of any device is intended for configuration, initialization, and catastrophic
error-handling functions only. Access to the PCI configuration space should be limited to initialization and
error-handling software.
17.4.2.11.1 PCI Configuration Space Header
The first 64 bytes of the 256-byte configuration space consists of a predefined header that every PCI device
must support. The predefined header for all PCI devices is shown in
predefined header are defined the same for all PCI devices; the remaining 48 bytes of the header may have
differing layouts depending on the function of the device. Most PCI devices use the configuration header
