==== Forcing a software reset using an external signal ====
As described before, GPIO1_IO08 is used by internal watchdog for triggering a software reset using [[Pinout_(AXEL_ULite)#PMIC_PWRON|PMIC_PWRON]].
The same input signal, can be used with an external push-button for triggering a software reset too.
[[Pinout_(AXEL_ULite)#PMIC_PWRON|PMIC_PWRON]] has an internal pull-up (see [[Reset_scheme_(AXEL_ULite)#Reset_scheme_and_control_signals|Reset scheme]]) and must be driven with an open-drain signal
