SDIO Host and Slave Controller question

[chintan_anrim]

Hi,

Our application needs both the SDIO slave controller (to appear like a SD card to a host), and the SD Host controller (to interface with an eMMC device). Although there isn't any explicit mention of mutual exclusivity, it seems that the device pins are the same for both these peripherals, which would mean only one can be supported any given time. Is that correct?

In other words can both the SDIO slave controller and SD Host controller be used simultaneously, or is it an either/or scenario?

Thanks
