   The board will be reset when it wakes up from power off.

   (via direct pin interrupt or via a command) to enter and exit standby.
-  Sleep modes allow a significant drop in the power usage of a board while it does nothing waiting for an event to happen. Battery powered application can take advantage of these modes to enhance battery life significantly.

+  In this sketch, the internal RTC of the SAMD chip will wake up the processor every 20 seconds.
   Before going to sleep, the SAMD chip tells the MIPS CPU to standby too.
   Please note that, if the processor is sleeping, a new sketch can't be uploaded. To overcome this, manually reset the board (usually with a single or double tap to the RESET button)
