5.4.1
Table 5.7 shows the sources that start the interrupt exception handling. They are NMI, user break,
IRQ, and on-chip peripheral modules.
Table 5.7
Note:
All interrupt sources are given different vector numbers and vector table address offsets. For
details on vector numbers and vector table address offsets, see table 6.3 in section 6, Interrupt
Controller (INTC).
