You can not use MMC or SD Cards in UART-Mode, because MMC/SD need SPI.
But in the driver there is also a build-in Soft-SPI. With them you can use four other pin (with normal I/O adress, not over &H60) to attache the Card.

Please check the File config_MMC_bas. Here you find information how to change to Soft-SPI and of course you have to set your pins.
