Display Subsystem Functional Description
This section describes the functions of the LCD and TV display supports by describing the following
modules: display controller, DSI protocol engine, DSI PLL controller, DSI complex I/O, RFBI and video
encoder.
The functions of the display controller are common to both LCD and TV data paths; the RFBI are
LCD-specific; and the video encoder functions are specific to the TV set.
