Looking at the LCP user manual (Page 1074) there is a line that says "The supply voltage VDD must be equal or lower than VDDA." I can find no similar statement in the datasheet; Table 12 (p. 79) gives the VDDA range as 2.7 - 3.6 V, making no mention of VDD.
I was wondering what issue this may cause moving forward. I missed this line while doing the first prototype spin and have VDD running at 3.3v and VDDA running at 3.0v. Pushing forward with testing on this first spin I would like to know what issues I should expect to see with this configuration. So far validation has yet to present any issues.
