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 USB features:
The USB UCPD cannot be operated simultaneously with full JTAG (JTDI).
• If PA15 is used as USB_CC1 (USB peripheral), JTDI cannot be used for JTAG peripheral.
The USB UCPD imposes some restrictions to the ARDUINO
• If PB5 is used as USB_DBn (USB peripheral) and JP5 is OFF, ARDUINO
be used, and STMod+ SPI3_MOSIP cannot be used.
6.9 microSD™ card
6.9.1

Description

The CN1 slot for the microSD
with SD Memory Card Specification Version 4.1: SDR104 SDMMC_CK speed limited to the maximum allowed I/O
speed. UHS-II mode is not supported.
6.9.2

Operating voltage

The SD card interface is only compatible with the 3.3 V voltage range, from 2.7 to 3.6 V.
The SD card interface does not support the MCU low voltage 1.8 V range.
6.9.3

SD card interface

The SD card interface is used in 4 data lines D [0:3], one CLK, one CDM, and a card detection signal.
Table 18 describes the HW configuration for the SDIO interface.
