MPC8548E Interrupt Controller

The MVME4100 uses the MPC8548E 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 MPC8548E Reference Manual listed in
for additional details regarding the operation of the MPC8548E PIC.
