PRODUCTION DATA.
For crystal oscillator components, see Section 5.10. If RTC domain is expected to be maintained after shutdown, VCC7 must have enough capacitance to make sure that when supply is switched off, voltage does not fall at a rate faster than 10 mV/ms. This makes sure that RTC domain data is maintained.
