32.768 kHz low frequency clock
The evaluation board has a 32.768 kHz crystal connected to the NORA-W10 module to allow use of
the external crystal oscillator option to source the RTC clock. The other options to source the RTC
clock are from the internal slow RC oscillator and the internal fast RC oscillator divided clock.
