Advanced Configuration and Power Interface Specification

Platform Communications Channel (PCC)
As an example, the following resource template refers to the field occupying bits 8 through 15 at
address 0x30 in PCC subspace 9:
ResourceTemplate()
{
Register (
PCC, //AddressSpaceKeyword
8, //RegisterBitWidth
8, //RegisterBitOffset
0x30, //RegisterAddress
9 //AccessSize (subspace ID)
)
}
Note that the PCC address space may not be used in any resource template or register unless the
register/resource field explicitly allows the use of the PCC address space.
