Notes: 1. VDDIO is the supply voltage for the following GPIO-pins: P1, P2, P8, P12, P14, P16, P17, P18, P19, P20, P21, P23, P24,
P25, P26, P27 and P29
2. Values defined for operating the USB interface. Otherwise VDD_USB may be connected to 1.8V or 0V supply.
3. Supply voltage VBAT18 for backup domain is generated internally by the LDOBAT.
