1. When the ADC is used, refer to Table 51: ADC characteristics.
2. It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV
between VDD and VDDA can be tolerated during power-up and operation.
3. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax.
4. In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax.
