The K64's SDHC states that it is compliant with MMC System Specification 4.2/4.3
I am looking into interfacing the K64's SDHC with a emmc device meeting specification 5.1.
I would like to use the 8 bit data interface.
I have not been able to find any information as to interfacing a 5.1 device with a 4.3 version controller.
Can this be done?
What are the pro/cons associated with an "old" SDHC controller mating with the latest emmc devices.
Thanks in advance for any replies.
