I/O restriction to other features

Caution: Due to the sharing of some I/Os of STM32L562QEI6QU by multiple peripherals, and because
STM32L562QEI6QU only supports one DFSDM interface, the following limitations apply in using the Audio
DFSDM features:
The U16 onboard MEMS, the MEMS module on CN2 and the STMod+ DFSDM interface cannot be operated
simultaneously.
