→PORSTn (J2.114)
* a multi-rail voltage monitor that monitors 3.3VIN power rails and all of the rails generated by Bora's PSU. This monitor
** in case of a power glitch, asserts MEM_WPn signal in order to prevent any spurious write operation on flash memories too. MEM_WPn is 3.3V, push-pull, active low.
** has a timeout (set through an on-board capacitor) of about 1ms200 ms.
** provides MRSTn debounced input for manual reset (for example to connect a push-button). This signal is pulled-up to 3.3VIN through a 2.2kOhm resistor.
* a watchdog timer (Maxim MAX6373). For more details please refer to [[Watchdog_(Bora)|Watchdog]] section.
