+ *
+ * Interface for Real Time Timer (RTT) controller.
+ *
+ * \par Usage
+ *
+ * -# Changes the prescaler value of the given RTT and restarts it
+ *    using \ref RTT_SetPrescaler().
+ * -# Get current value of the RTT using \ref RTT_GetTime().
+ * -# Enables the specified RTT interrupt using \ref RTT_EnableIT().
+ * -# Get the status register value of the given RTT using \ref RTT_GetStatus().
+ * -# Configures the RTT to generate an alarm at the given time
+ *    using \ref RTT_SetAlarm().
