Chipset Configuration Registers
7 Chipset Configuration Registers
This chapter describes all registers and base functionality that is related to chipset
configuration and not a specific interface (e.g., LPC, PCI, or PCI Express*). It contains
the root complex register block that 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-(DWord) bit quantities. Burst accesses are
not allowed.
