SM32L4 interface with an eMMC

Hello there,

I am using STM32L452. I would like to interface with a SanDisk eMMC memory (SDINBDG4-8G-XI1).

In cubeMX, when I configure the project and choose SDMMC1->MMC 4 bits Wide bus, I get the following:


Does that mean that there is no ready HAL functions? Or, for instance, can I use the SD 4 bits Wide bus for communication? Are those interfaces compatible in STM32?

I would appreciate all help.
