MMC has nothing to do with this. 4-bit SPI is for quad-SPI capable devices. This includes NOR flash chips, but not MMC/SD.
I don't get that comment.But can this also be reduced for on the same SPI I got other device which do not need to fast speed?
You should use the SDMMC Host peripheral then, not the SPI peripherals. Suggest you read at least the top part of this.As this is a new board, we aim to design it for max performance.
I will be using the SD card as temp storage for Audio and possibly Videos/Photos in the future.
