RTC - REAL TIME CLOCK
The ADE75XX/ADE71XX has an embedded Real Time Clock (RTC) – see Figure 75. The external 32.768 kHz crystal is used as the clock
source for the RTC. Calibration is provided to compensate the nominal crystal frequency and for variations in the external crystal
frequency over temperature. By default, the RTC is maintained active in all the Power Saving Modes. The RTC counters retain their
values through watchdog resets and external resets and are only reset during a power on reset.
