3.2.3.2 Slow Clock Circuitry

The slow clock oscillator is implemented with a NX2012SA-32.768K crystal device.

For evaluation purposes, the user can mount instead a MEMS (Micro Electro-Mechanical System DSC6003MA3B-032K768), using the PCB footprint reservation (Y4). In that case, remove crystal Y1 and capacitors C66 and C72, and populate resistor R38 and capacitor C77 with the appropriate MEMS (Y4).
