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.
Chipset Configuration Registers (Memory Space)
Address locations that are not shown should be treated as Reserved (see
for details).
