This option enables wake up from deep sleep from GPIO3. They 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.

bool "Use internal pull-up/downs for EXT1 wakeup source"
default n
depends on EXAMPLE_EXT1_WAKEUP
help
When using EXT1 wakeup source without external pull-up/downs, you may want to make use of the internal
ones.
However, the RTC IO reside in the RTC Periph power domain. Enable this option to force that power domain
ON during deep sleep. Note that this will increase some power comsumption, so it's still suggested to use
external ones instead.
EXT0 wakeup source resides in the same power domain as RTCIO (RTC Periph), so internal pull-up/downs are
always available. There's no need to explicitly force it on for EXT0.
