Figure 10-2 displays the interrupt sources for the MPC5553. Figure 10-3 displays the interrupt sources for
the MPC5554. Refer to Table 10-9 for interrupt source vector details.

Figure 10-3. MPC5554 INTC Software Vector Mode
Two modes are available to determine the vector for the interrupt request source: software vector mode
and hardware vector mode. In software vector mode, as shown in Figure 10-2, the e200z6 branches to a
common interrupt exception handler whose location is determined by an address derived from special
purpose registers IVPR and IVOR4. The interrupt exception handler reads the INTC_IACKR to determine
