This read-only register identifies the manufacturer of the device. PCI Special Interest
Group (PCI-SIG) assigns valid vendor identifiers to ensure the uniqueness of the
identifier. The bit description is shown in
This is a 2-byte read-only register that identifies a particular device. The identifier is
allocated by NXP Semiconductors.
This is a 2-byte register that provides coarse control over the ability of a device to
generate and respond to PCI cycles. The bit allocation of the Command register is given
in
the PCI bus for all accesses, except configuration accesses. All devices are required to
support this base level of functionality. Individual bits in the Command register may or may
not support this base level of functionality.
