8.2.1.2 Device ID register
8.2.1.3 Command register
Table 4.
Legend: * reset value
This is a 2 B read-only register that identifies a particular device. The identifier is allocated
by NXP Semiconductors.
Table 5.
Legend: * reset value
[1]
This is a 2 B 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
When logic 0 is written to this register, the device is logically disconnected from 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.
