A plurality of key register sections in a processor respectively associated with different machine-sensed types of accesses to a main storage of a computer system. A processor address key register (AKR) includes the following sections: (1) a section associated with an instruction-fetch type access, (2) a section associated with a source-operand fetch type access, and (3) a section associated with a sink-operand store/fetch type access. Other key register sections may be associated with respective sub-channel store/fetch type accesses.
