TMS320F28P650DK: Internal vs external VDD supply

Tool/software:

Hello,

Is there any performance difference between using the internal 1.2V VDDReg vs using an external 1.2V regulator? It seems like using the internal 1.2V regulator is actually lower power, but are there any performance tradeoffs between using either?

    There are no performance drawbacks with using the 1.2V internal regulator, I think it is generally advisable to use the internal regulator.
