follow-on from: STM32L562: frequency error when outputting LSE via MCO (crystal mode); bypass OK (solved).
Hi all,
When LSE is configured in crystal mode, I tried probing OSC32_OUT directly with an oscilloscope probe, but I see no visible waveform (it may be too small or the probing may be loading the oscillator).
Could anyone share:
Is there any typical/expected voltage amplitude range on OSC32_OUT (e.g., mVpp / Vpp) when LSE crystal mode is running normally on STM32L562 / STM32L5?
Thanks!
