The LCD_C driver generates the segment and common signals required to drive a liquid crystal display (LCD). The LCD_C controller has dedicated data memories to hold segment drive information. Common and segment signals are generated as defined by the mode. Static, and 2-mux up to 4-mux LCDs are supported. The module can provide an 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 contrast by software. The module also provides an automatic blinking capability for individual segments in static, 2-mux, 3-mux, and 4-mux modes.
To reduce system noise the charge pump can be temporarily disabled. Table 6-18 lists the available automatic charge pump disable options.
