SD/MMC/SDIO module
This block provides the power supply (1.8 V, 2.85 V or 3 V) and signal shifting functions
required to connect any of the following peripherals to the multimedia processor:
Cards detection is automatically done by the multimedia processor system. Following a card
detection, the multimedia processor starts the SD/MMC application by writing in the SD
MMC control register (
