ECC signals from memory devices must be disconnected.
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.
Notes
1.
External timers are implemented in a PLD.
2.
External UARTs are implemented using a QUART.
Refer to the
MPC8540 Reference Manual
listed in
Appendix A,

, for additional
details regarding the operation of the MPC8540 PIC.
