Preliminary Technical Data
REAL TIME CLOCK
The ADE7566/ADE7569 have an embedded real time clock
(RTC) as shown in Figure 88. 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 power-saving modes. The RTC
counters retain their values through watchdog resets and
external resets. They are only reset during a power-on reset.
