Notes
The configurable wakeup lines are edge-triggered. No glitch
must be generated on these lines. If a rising edge on a
configurable interrupt line occurs during a write operation in
the EXTI_RTSR register, the pending bit is not set. Rising and
falling edge triggers can be set for the same interrupt line. In
this case, both generate a trigger condition.
