Notes:
1. PD = internal pull-down resistor, PU = internal pull-up resistor, OH = switched to Output High at reset
2. 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
3. VDD_USB is the supply voltage for the following USB pins: USB_DM and USB_DP. For operation of the USB interface, sup-
ply of 3.0V to 3.6V is required.
