Hello,
I am working with a custom board that has the nRF52840 (via the ISP1807-LR-RS module). This board has the SIT1552AI-JE-DCC-32.768E MEMS TCXO. This TCXO chip has a single clock out line connected to pin P0.30 of the nRF52840. I see from the datasheet for nRF52840 that this is not one of the XL* lines. Is it still somehow possible to configure prj.conf and device tree to get the MCU to use this single-output TCXO as the 32.768 kHz clock source? I have tried looking for samples in the SDK that demonstrate this, but haven't found anything that looks to me like it pertains to my situation/setup (possibly I just completely missed or didn't recognize one that is actually there).
I am happy to answer questions and provide additional info as needed. Thanks for your help.
