Bits 31:8 Reserved, must be kept at reset value.
Note:
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 to 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.
