To configure the CLAD:
1. Switch to free-run mode to avoid spurious, invalid output frequencies [CLAD_CR; addr 02].
2. Choose a CLADO output frequency. See the CLAD Frequency Select register [CSEL; addr 03] for a list of all
3. Configure OSEL to select the CLADO output frequency.
4. Select the desired CLAD timing reference frequency from
5. Configure RSCALE, VSCALE, VSEL from
