Interrupt Controller

The MVME2502 uses the MPC8548E integrated programmable interrupt controller (PIC)
to manage locally generated interrupts. Currently defined external interrupting devices,
interrupt assignments, along with corresponding edge/levels, and polarities are shown in
the following table.
