Abstract: A media peripheral interface for communication between a processor and a peripheral device includes a clock port, a plurality of data I/Os, and a data strobe port. The clock port is operative to transfer a clock signal to the peripheral device. The data I/Os are provided for command transfer to the peripheral device and for data transfer to and from the peripheral device. The data strobe port is operative to transfer a data strobe signal to or from the peripheral device according to an instruction that the processor issues to the peripheral device. According to the clock signal, command information transferred via the data I/Os is captured. According to rising edges and falling edges of the data strobe signal, data transferred via the data I/Os are captured.
