CPC:

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 input/output bus > using burst mode transfer, e.g. direct memory access , cycle steal (G06F13/32 takes precedence)

CPC subdivides this area 4x more granularly than IPC with 3 additional codes.

3 codes are CPC-only extensions.

IPC defines codes here since 1985.
