Notes:
1. The maximum difference between VSS and VSSA, and between VDD and VDDA, must be less than 0.6 V
in module. The minimum value of VDDA is 3 V.
2. VDD depend on fOSC , see Figure 11.3
3. The fOSC min allowed to use the A/D Converter is 2 MHz
4. Lower VDD decreasing fosc (see Figure 11.3). Data illustrated in the figure are characterized but not test-
ed.
