Register Definitions
This section describes the registers within the SiI3512 controller.
PCI Configuration Space
The PCI Configuration Space registers define the operation of the SiI3512 device on the PCI bus. These registers are
accessible only when the SiI3512 controller detects a Configuration Read or Write operation, with its IDSEL asserted, on
the 32-bit PCI bus.
Table 16 outlines the PCI Configuration space for the SiI3512 controller.
