(1) It is recommended to power AVCC and DVCC from the same source. A maximum difference of 0.3 V between AVCC and DVCC can be
tolerated during power up and operation.
(2) USB operation with USB PLL enabled requires PMMCOREVx ≥ 2 for proper operation.
(3) Modules may have a different maximum input clock specification. Refer to the specification of the respective module in this data sheet.
