Place a minimum amount of decoupling capacitance on VDD. See the CVDD TOTAL parameter in Power Management Module Electrical Data and Timing.
In external VREG mode, the actual amount of decoupling capacitance to use is a requirement of the power supply driving VDD.
Either of the configurations outlined below is acceptable:
