Information Technology - Microprocessor Systems - Control and Status Registers (CSR) Architecture for Microcomputer Buses (same as ISO/IEC 13213-1994) / Note: Approved 1994-12-12.
This standard defines an organized, common register set to be used for control, configuration, identification and diagnostics between nodes on a system bus interconnect. The CSR architecture provides a scalable, extensible framework for interoperability between nodes of a variety of buses.
