SDIO,SD1bit,UART4 Disable.

I want to use uart4_tx and sdio at the same time.

But, in cubemx(6.2.1),

SDIO->Mode: SD 1 bit

UART4->Mode: only Disable.

If the SDIO initialization function is not executed and only the"uart4_init(36,250000);" function is executed, uart4_tx can successfully send data.
