Introduced: January 1990
Full Title
Full titles differ between systems:
Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units > Handling requests for interconnection or transfer > for access to common bus or bus system > with decentralised access control
Interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units (interface circuits for specific input/output devices G06F3/00 ; multiprocessor systems G06F15/16 ) > Handling requests for interconnection or transfer > for access to common bus or bus system > with decentralised access control
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
IPC defines codes here since 1990.
