The LCD_B driver generates the segment and common signals that are required to drive a liquid crystal display (LCD). The LCD_B controller has dedicated data memories to hold segment drive information. Common and segment signals are generated as defined by the mode. Static, 2-mux, 3-mux, and 4-mux LCDs are supported. The module can provide a LCD voltage independent of the supply voltage with its integrated charge pump. It is possible to control the level of the LCD voltage, and thus the contrast, by software. The module also provides an automatic blinking capability for individual segments.
