6.6.1
Interrupt sources are NMI, IRQ0 to IRQ11, and on-chip peripheral modules, as shown in table 6.7.
Table 6.7
Note:
Different vector numbers and vector table offsets are assigned to different interrupt sources. For
vector number and vector table offset, refer to table 7.2, Interrupt Sources, Vector Address
Offsets, and Interrupt Priority in section 7, Interrupt Controller.
6.6.2
Interrupts are controlled by the interrupt controller. The interrupt controller has two interrupt
control modes and can assign interrupts other than NMI to eight priority/mask levels to enable
multiple-interrupt control. The source to start interrupt exception handling and the vector address
differ depending on the product. For details, refer to section 7, Interrupt Controller.
