Name
The CX28560 is a single function PCI device that provides the necessary
configuration space for a PCI bus controller to query and configure the CX28560’s
PCI interface. PCI configuration space consists of a device-independent header region
(64 bytes) and a device-dependent header region (192 bytes). The CX28560 provides
the device-independent header section only. Access to the device-dependent header
region results in 0s being read, and no effect on writes.
Three types of registers are available in the CX28560:
Sixteen dword registers make up the CX28560’s PCI Configuration Space.
The tables below specify the contents of these registers:

Read-Only (RO)—Return a fixed bit pattern if the register is used or a 0 if the
register is unused or reserved
Read-Resettable (RR)—Can be reset to 0 by writing a 1 to the register
