3.3.1
The interrupt sources include 13 external interrupts (WKP
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:

Both internal and external interrupts can be masked by the I bit of CCR. When this bit is set to
1, interrupt request flags are set but interrupts are not accepted.
The external interrupt pins IRQ
sensing or falling edge sensing.
