+/** 08_wakeup
+ *
+ * The LED is "off" for 2 seconds (the target spends this interval in deepsleep() mode)
+ * then the LED is "on" for the other second. Awakening is arranged by using the WakeUp
+ * class library.
+ *
+ * Author: Erik Olieman
+ * Link: https://developer.mbed.org/users/Sissors/code/WakeUp/
+ * Minor modifications: I. Cserny
+ *
+ * A note about the implementation of the WakeUp library:
+ * ------------------------------------------------------
+ * The KL25z target board uses the same LPTMR for both WakeUp and for ticker generation.
+ * The WakeUp code is nice, and it will backup the old values when being set, and restore
+ * those after waking up, allowing you to continue using your ticker, and a ticker which
+ * was already set will continue again. However you are not allowed to set a new ticker
+ * after you already set WakeUp, since this will give clashes. Do you for whatever reason
+ * need to do it (for example you set WakeUp, and then you wake using an InteruptIn),
+ * you can disable the WakeUp timer and restore the ticker functionality by setting
+ * WakeUp for 0 seconds.
