The interrupt sources include 13 external interrupts (WKP
IRQAEC) and 9 internal interrupts from on-chip peripheral modules. Table 3.2 shows the interrupt
sources, their priorities, and their vector addresses. When more than one interrupt is requested, the
interrupt with the highest priority is processed.
The interrupts have the following features:
• Internal and external interrupts can be masked by the I bit in CCR. When the I bit is set to 1,
• IRQ
interrupt request flags can be set but the interrupts are not accepted.
