CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (LCD Driver)
(3) Static drive
The S1C63653 provides software setting of the LCD static drive. However, this function is available
only when "External power supply 1/2 bias (for 3.0 V panel)" is selected by mask option.
To set in static drive, write "1" to the common output signal control register STCD. Then, by writing
"1" to any one of COM0 to COM5 (display memory) corresponding to the SEG terminal, the SEG
terminal outputs a static on waveform. When all the COM0 to COM5 bits are set to "0", the SEG
terminal outputs a dynamic off waveform.
Figure 4.8.3.5 shows the static drive waveform.

Note: To use the static drive function, select the "External power supply 1/2 bias (for 3.0 V panel)" mask
option. When an option for using the internal power supply or a 1/3 bias external power supply is
selected, static drive cannot be set using the STCD register.
