Hello,
The SDCard driver seems to support two different interface modes:
SD_INTERFACE_SD_MMC_1BIT and SD_INTERFACE_SD_4BIT. The fourth bit interface
is faster but only compatible with SD cards and not with MMC cards. The
question is:
Does the SDcard driver do the automatic selection of the interface mode
based on automatic detection of the card capabilities, or it's necessary to
call SDSetCardFeature, or modify a registry setting, to set the proper
interface mode?
