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 ground

3. Supply voltage VBAT18 for backup domain is generated internally by the LDOBAT
