RTC Definitions
The following definitions are helpful when using the RTC module.
RTC HV
The RTC HV is the portion of the RTC which runs on 3.3 V domain and contains the logic for RTC counting/
clock functionality
RTC LV
The RTC LV operates on the core voltage supply and provides the control/access functionality and user interface to
the application
Oscillator
The oscillator is the heart of the RTC. It works with the dedicated external crystal to generate a 32768 Hz signal
which is divided down to a 1Hz clock used to operate the rest of the RTC
