(1) The external reference is used during ADC conversion to charge and discharge the capacitance array. The input capacitance (CI) is also the dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the recommendations on analog-source impedance to allow the charge to settle for 12-bit accuracy.
(2) Connect two decoupling capacitors, 10 µF and 470 nF, from VeREF+ or VeREF– to AVSS to decouple the dynamic current required for an external reference source if it is used for the ADC12_B. Also see the MSP430FR58xx, MSP430FR59xx, and MSP430FR6xx Family User's Guide.
