Interrupts
A list of interrupt sources is given in
source. Interrupts are serviced according to their order of priority, starting with I0, which has
the highest priority, and so to I12, which has the lowest priority.
The following list describes the origins for each interrupt level:
Exit from Halt mode may only be triggered by an External Interrupt on one of the following
ports: PA0-PA7 (I0), PB0-PB1 (I0), or by an Internal Interrupt coming from CAN peripheral
(I1).
If more than one input pin of a group connected to the same interrupt line are selected
simultaneously, the OR of this signals generates the interrupt.
