Bias Control and Applied Voltage to LCD Power
Input Pins
To the LCD power input pins (VL1–VL3), apply the voltage value shown
in Table 8 according to the bias value.
Select a bias value by the bias control bit (bit 2 of the LCD mode
register).
Common Pin and Duty Ratio Control
The common pins (COM0–COM3) to be used are determined by duty
ratio.
Select duty ratio by the duty ratio selection bits (bits 0 and 1 of the
LCD mode register).
When selecting 1-duty ratio, 1/1 bias can be used.
