+ *  \brief Real Time Alarm Clock
+ * 
+ * Implementation of the Real-Time Alarm Clock as per SNP Specifications.
+ * It provides real-time and phase controlled timer module while it 
+ * cooperates with hardware RTC for low-power operation.
+ * 
+ * It provides a replacement for a system 32-bit UTC time/date counter.
+ * 
+ * It runs at maximum STM32 allowed precision of 16384 Hz, providing 
+ * resolution of 61 us, required by the Sensor Network Protocol.
