VDD

1. UFQFPN32 pinout differs from other STM32 devices except STM32L07xxx and STM32L8xxx.

2. PA4 offers a reduced touch sensing sensitivity. It is thus recommended to use it as sampling capacitor I/O.

3. These pins are powered by VDD_USB. For all characteristics that refer to VDD, VDD_USB must be used instead.
