An overview of the MPC561/MPC563 interrupt structure is shown in
receives interrupts from USIU internal sources, such as PIT, RTC, from the UIMB module (which has its
own interrupt controller) or from the IMB3 bus (directly from IMB modules) and from external pins
IRQ[0:7].

Significant interrupt latency reduction from that of the MPC555.
Simplified interrupt structure
Up to 48 different interrupt requests
Splitting of single external interrupt vector into up to 48 vectors, one for each source
Automatic lower priority requests masking
Full backward compatibility with MPC555/MPC556 (enhanced mode is software programmable.)
