Note 2: The operating power supply current includes the total current through all CV_DD, MV_DD, DV_DD and AV_DD
power supply pins.
Note 3: Design and specify constants according to the crystal oscillator to be connected.
Note 4: The values are guaranteed when CV_DD = MV_DD = DV_DD = AV_DD = 3.0 to 3.6 V, Ta = -40 to 85°C.
Note 5: The values are guaranteed when CV_DD = MV_DD = DV_DD = AV_DD = 1.8 to 3.6 V, Ta = -30 to 75°C.
