Abstract
A host device includes a first serial peripheral interface (SPI) and a second SPI to communicate with an embedded multimedia card (eMMC) device. The host device has a mode controller that controls the first SPI to toggle between first transmission and first reception modes for command transmission and response reception, respectively. The mode controller controls the second SPI to toggle between second transmission and second reception modes for data transmission and data reception, respectively.
