® ItIIOTOROLA Advance Information INTELLIGENT PERIPHERAL CONTROLLER The MC68120/MC68121 Intelligent Peripheral Controller (lPCI is a general purpose, mask programmable peripheral controller. The IPC provides the interface between an M68000 or M6800 Family microprocessor and the final peripheral devices through a system bus and control lines. System bus data is transferred to and from the IPC via dual-port RAM while the software utilizes the semaphore registers to control RAM tasking or any other shared resource. Multiple operating I modes range from a single chip mode with 21 I/O lines and 2 control lines to an expanded mode supporting an address space of 64K bytes. The MC68120 has 2K bytes of on-chip ROM to make full use of all operating modes.
