16.7.1 Static display example
the segment signals (SEG0 to SEG23) and the common signal (COM0). This example displays data "12.3" in the LCD
panel. The contents of the display data memory (F0400H to F0417H) correspond to this display.
it is necessary to apply the select or deselect voltage to the SEG8 to SEG15 pins according to Table 16-5 at the timing of
the common signal COM0; see Figure 16-15 for the relationship between the segment signals and LCD segments.

Figure 16-16 shows how the three-digit LCD panel having the display pattern shown in Figure 16-15 is connected to
The following description focuses on numeral "2." (
According to Table 16-5, it is determined that the bit-0 pattern of the display data memory locations (F0408H to
Figure 16-17 shows the LCD drive waveforms of SEG11 and SEG12, and COM0. When the select voltage is applied
COM1 to COM3 are supplied with the same waveform as for COM0. So, COM0 to COM3 may be connected together
