Hi,
Is VLO independent internal oscillator clock source or is it derived from DCO clock source when there is no external crystal is connected ?
VLOCLK is a separate onboard oscillator from DCO. Not related to DCO in any way. It generates a ~10-12KHz signal that may vary widely based on temperature/voltage/etc. and it can only source the ACLK. It also cannot run at the same time as the 32.768KHz LFXT1, to my knowledge.

All this and not only, you can find out reading User's Guide :)
