Table 16:
Location of SD/ MMC Card Interface Signals (SDMMC5)
Note:
The signal level of the SD / MMC card interface SDMMC5 is 1.8 V. Thus integration of an SD / MMC card slot on
custom target hardware requires level shifters supplied with VCC_1V8_IO (X1B30) at one of the supply rails.
Please take care to not load the reference voltage VCC_1V8_IO too heavily to avoid any disfunction or damage
of the module. The maximum load is 400 mA.
