Notes:

1. PD = internal pull-down resistor, PU = internal pull-up resistor, OH = switched to Output High at reset

2. VBAT18 represent the internal power supply of the backup power domain, see section “Power Supply” on page 20.

3. VDD_USB is the supply voltage for following the USB pins: USB_DM and USB_DP, see section “Power Supply” on page

20. For operation of the USB interface, supply of 3.0V to 3.6V is required.

4. 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, see section “Power Supply” on page 20.
