(*1) Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses
beyond the Recommended Operating Ranges limits may affect device reliability.
(*2) Follow the operating frequency specifications because the operating frequency ranges are specified according to the operating voltage
ranges.
(*3) Regarding Xtal frequency range, refer to the detailed datasheet.
(*4) While USB is not used.
(*5) While USB is used (including USB suspend mode)
(*6) While used as GPO (general purpose output) the output of which can be controlled by registers
(*7)  Power domains of Vdd1, AVddUSBPHY1=DVddUSBPHY1, AVddPLL1, AVddPLL2, AVddPLL3, VddXT1 are divided, and different
voltage can be supplied.
 Power domains of Vdd2, VddSD0, VddSD1, VddSD2, VddQSPI, AVddADC, AVddUSBPHY2, AVddPLL3,
AVddDAMPL=AVddDAMPR are divided, and difference voltage can be supplied.
 If power is supplied to one of the power supply pins above, all of other power supply pins should be supplied.
 VddRTC can be supplied if BACKUPB is set to low, while other power supply pins are not supplied.
