4.1.3 Exception Vector Table
The exception sources are classified as shown in figure 4-1. Different vectors are assigned to
different exception sources. Table 4-2 lists the exception sources and their vector addresses.
Exception
sources
• Reset
• Interrupts
• Trap instruction
External interrupts: NMI, IRQ₀ to IRQ₄
Internal interrupts: 21 interrupts from on-chip
supporting modules
