Figure 18-5. Configuration of Common Signal Output and Segment Signal Output Timing Control Blocks
Figure 18-5 shows the common signal output and segment signal output timing control blocks.
The common signal output timing control block controls the common signal output timing of the COM0 through
The segment signal output timing control block controls the segment signal output timing of the LCD0 through
The common and segment signals are output when the LCDEN flag of the LCD driver display start register is set
When this flag is reset to “0”, all the LCD display dots can be extinguished (refer to Figure 18-6).
When LCD display is not carried out, the COM0 through COM3 and LCD0 through LCD14 pins output low level.
