The SNVS LDO output (VDD_SNVS_CAP) requires an external capacitor. Freescale's updated recommendation is that this should be a single 0.22 uF capacitor.
Freescale is working to get documents in alignment. As of Feb 2013, some documents (such as schematics or user guides) show a single 0.22 uF capacitor, others do not.
