49 / 74 page  The accompanying LCD Memory Map diagrams shows how the internal LCD Memory is mapped to the Segments and Commons of the display for the devices. LCD Memory Maps for devices with smaller memory capacities can be extrapolated from these diagrams. LCD Registers Control Registers in the Data Memory, are used to control the various setup features of the LCD Driver. There is one control register for the LCD function, LCDC. Various bits in this registers control functions such as bias type as well as overall LCD enable and disable. The LCDEN bit in the LCDC register, which provides the overall LCD enable/disable function, will be effective when the device is in the Normal or HALT Mode. The LCDWT bit in the same register is used to select whether Type A or Type B LCD control signals are used. The register, SEGC is used to determine if the output function of display pins SEG0~SEG7 are used as segment drivers or I/O functions. Clock Source The LCD clock source is the LXT Oscillator divided by 8 to generate an ideal LCD clock source frequency of 4kHz.
