SDIO port with 2 SDCARD Chip Select

Hello, 

I have a STM32F411 and I am ready using the SDIO port, 

I would like to connect 2 SDCARD to the SDIO port and be able to switch from one to another like using a CS Chip select GPIO. 

Is it possible ? how would I do that ? 

Thanks 

Vincent

Bonjour @vbesson 

As you can see on the paragraph 3.26 of the DS10314, you can only use only one SD Card each time.

Best Regards.
