Central Processing Unit:

Internal Interrupt Sources

All interrupt sources are prioritized and bits are set in the Interrupt Pending register (SIPNR).
The relative priority of the FCCs, MCCs, and SCCs can be modified per the XCCx and YCCx
groups and spreads, and one interrupt source can be assigned the highest priority.

External Interrupt Sources

The 16 external interrupts are connected to the MPC8560 through the parallel
I/O Port C pins.
