14.4 COMP interrupts
The comparator outputs are internally connected to the Extended interrupts and events
controller. Each comparator has its own EXTI line and can generate either interrupts or
events. The same mechanism is used to exit from low-power modes.
Refer to Interrupt and events section for more details.
