The MB1263/CN9 slot for microSD card is routed to the STM32MP157FAA1 SDMMC1 port. This SD card
interface is compliant with SD Memory Card Specification V
ersion 3.01, UHS-I, all operation modes up to SDR104
and DDR50. The SD card interface is compatible with 1.8 V or 2.9 V signal levels.
6.14.1 SD card interface
The SD card interface, SDMMC1, is 4-bit wide with level shifter support, in order to connect to an SD 3.0-
compliant bidirectional dual voltage level translator
, interfacing with the memory card inserted in the SDCARD
connector.
Table 18 describes the I/O for the SDMMC1 interface.
