I/O restriction to other features

Caution: Due to the sharing of some I/Os of STM32L562QEI6QU by multiple peripherals, the following limitations apply in
using the STMod+ features:
• The STMod+ cannot be operated simultaneously with the UCPD function.
• The STMod+ cannot be operated simultaneously with the Pmod
• The STMod+ cannot be operated simultaneously with the SDCARD function.
