A block diagram of interrupts IRQ7 to IRQ0 is shown in figure 5.2.
5.4.2
The sources for internal interrupts from on-chip peripheral modules have the following features:
• For each on-chip peripheral module there are flags that indicate the interrupt request status,
• The interrupt priority level can be set by means of IPR.
5.5
Table 5.2 shows interrupt exception handling sources, vector addresses, and interrupt priorities.
For default priorities, the lower the vector number, the higher the priority. When interrupt control
mode 2 is set, priorities among modules can be changed by means of the IPR. Modules set at the
same priority will conform to their default priorities. Priorities within a module are fixed.
input
and enable bits that select enabling or disabling of these interrupts. They can be controlled
independently. When the enable bit is set to 1, an interrupt request is sent to the interrupt
controller.
Note: n = 15 to 0
