Runtime Registers

The registers listed in the Runtime Registers Register Summary table are for a single instance of the ACPI Embedded

Controller Interface (ACPI-ECI). The addresses of each register listed in this table are defined as a relative offset to the

host “Base Address” defined in Runtime Registers Address Range Table.

Note 9-3

The Base Address indicates where the first register can be accessed in a particular address space

for a block instance.
