MPC8540 Interrupt Controller

7.3 MPC8540 Interrupt Controller
The MVME3100 uses the MPC8540 integrated programmable interrupt controller (PIC) to
manage locally generated interrupts. Currently defined external interrupting devices and
interrupt assignments, along with corresponding edge/levels and polarities, are shown in
the following table.
