Hi Albert, Recommended decoupling capacitance is 10 uF + 100 nF as shown in Figure 16-11 of the User's Guide ( SLAU272 ) and Figure B-30 of the Hardware Tools User's Guide ( SLAU278 ). Section 5.3 of the device Datasheet ( SLAS639 ) notes that the capacitor ratio of VCC to VCORE (CVCC/CVCORE) is 10, and since the capacitance required at VCORE is 470 nF the smallest VCC decoupling capacitance allowed is 4.7 uF, however you should be wary of the capacitor's tolerances as they could put your system out-of-spec.
