Abstract
An apparatus and method for interfacing a host system having a system data bus, clock signals, and control signals to a parallel data bus is described. Setting configuration bits allows the interface apparatus to be programmed to operate as a transmitter or a receiver with selectable device interface modes. When operating as a transmitter, the interface apparatus combines and compresses the system data bus, clocks, and control signals to match the available width of the parallel data bus. When operating as a receiver, the interface receives signals from the parallel data bus and restores the original signals which were combined and compressed. The device interface modes are selectable to be compatible in different device and circuit configurations.
