INT Output is active LOW.
That means the falling edge of the INT signal is generated by the RV-3029.
When testing the time-accuracy by using INT signal it is mandatory to trigger on the falling edge of the
Interrupt signal.
The rising edge of the INT signal is generated when the MCU clears the Interrupt signal by software.
The timing of the rising edge depends on the MCU and must not be used to test the time-accuracy.
