17.4.2.11.3 Agent Accessing the PCI Configuration Space
When this device is configured as an agent device, it responds to a remote host-generated PCI
configuration cycle. This is indicated by decoding the configuration command along with PCI's IDSEL
being asserted. When the PCI controller detects an access to PCI CFG_DATA, it checks the enable flag
and the device number in the PCI CFG_ADDR register. If the enable bit is set, and the device number is
not 0b1_1111, the PCI controller performs a configuration cycle translation function and runs a
configuration-read or configuration-write transaction on the PCI bus. The device number 0b1_1111 is used
for performing interrupt-acknowledge and special-cycle transactions. See
Transactions,”
0x00), the PCI controller performs a type 0 configuration cycle translation. If the bus number indicates a
remote PCI bus (that is, nonlocal), the PCI controller performs a type 1 configuration cycle translation.
Note that in the following examples, the data in the configuration register is shown in little-endian order.
This is because all the PCI registers are intrinsically little-endian. External PCI masters that use the local
address map to access configuration space do not need to reverse bytes since byte lane redirection from
the little-endian PCI bus is performed internally.
Example: Configuration sequence, 4-byte data write to PCI register at address offset 0x14 of Device 1 on
PCI bus 0.
