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
If the signals GPIO15/ADC2-CH4 and GPIO16/ADC2-CH5 want to be used, the crystal can be removed
from the circuit by opening jumpers J19 and J21 and soldering across the normally open positions.
This connects XT-32k-p and XT-32k-n to the EVK pin socket J2 pin 5 and pin 6.
