6.4.1 SIU Interrupt Sources Priority
MPC555
USER’S MANUAL
The SIU has 15 interrupt sources that assert just one interrupt request to the RCPU.
There are eight external IRQ pins (IRQ[0] should be masked since it generates a NMI)
and eight interrupt levels. The priority between all interrupt sources is shown in
6-3.
