The RTC module can be used for different purposes:
• System clock to determine the current time and date,
optionally during idle mode, sleep mode, and power down mode
• Cyclic time based interrupt, to provide a system time tick independent of CPU
frequency and other resources, e.g. to wake up regularly from idle mode.
• 48-bit timer for long term measurements (maximum timespan is > 100 years).
• Alarm interrupt for wake-up on a defined time
