External Component Recommendation

For crystal oscillator components, see Section 5.12.

If RTC domain is expected to be maintained after shutdown, VCC7 must have enough capacitance to ensure that when

supply is switched off, voltage does not fall at a rate faster than 10 mV/ms. This ensures that RTC domain data is maintained.
