Chipset Configuration Registers
7 Chipset Configuration Registers
This section describes all registers and base functionality that is related to chipset configuration
and not a specific interface (such as LPC, PCI, or PCI Express*). It contains the root complex
register block, which describes the behavior of the upstream internal link.
This block is mapped into memory space, using register RCBA of the PCI-to-LPC bridge.
Accesses in this space must be limited to 32-(DW) bit quantities. Burst accesses are not allowed.
