Abstract
A communication protocol for multi-functional mini-memory cards is disclosed. Data is transferred through semi-duplex process and four bitstreams of data being transferred in parallel. A CLK signal is used as a base clock in data transfer. Each clock has four bits of data being transferred in parallel. In each bitstream, data is transferred as data packages. Endpoints are used as the data source and data sink in a transmitting end and a receiving end, respectively. A data package includes start bits, package identification codes, communication endpoints; data length, payloads, package status codes, data formats; and end bits.
