- **EXT1:** GPIO2 and GPIO4 should be connected to LOW to avoid floating pins. When triggering a wake up, connect one or both of the pins to HIGH. Note that floating pins may trigger a wake up.
- **GPIO:** If `EXAMPLE_GPIO_WAKEUP_HIGH_LEVEL` is selected in menuconfig, then connect `EXAMPLE_GPIO_WAKEUP_PIN` to HIGH to trigger a wake up; Otherwise, connect `EXAMPLE_GPIO_WAKEUP_PIN` to LOW to trigger a wake up.
- **GPIO:** In `Example configuration > GPIO wakeup configuration`, set **GPIO wakeup trigger type** to match how you drive `EXAMPLE_GPIO_WAKEUP_PIN`: for **High level**, hold the pin low before sleep then drive high to wake; for **Low level**, hold high then pull low; for **Rising/Falling/Any edge** (targets with `SOC_RTC_GPIO_EDGE_WAKEUP_SUPPORTED`), use an edge after a stable idle level as required by the selected mode.

Wake up sources that are unused or unconnected should be disabled in configuration to prevent inadvertent triggering of wake up as a result of floating pins.
