2.9.2 Asynchronous Edge Detection
When the asynchronous edge detection is enabled and the system is in Standby mode, only the first edge will be detected. The following edges are ignored until the system wakes up.
Work Around:
Use the asynchronous edge detection with debouncer enabled. It is recommended to set the DPRESCALER.PRESCALER and DPRESCALER.TICKON to have the lowest frequency possible. To reduce the power consumption, set the EIC GCLK frequency as low as possible or select the ULP32K clock (EIC CTRLA.CKSEL set).
