Bias Control and Applied Voltage to LCD Power Input
Pins
When the voltage is applied from the LCD power input pins
(VL1
VL3), set the VL pin input selection bit (bit 5 of the LCD
power control register) and VL3 connection bit (bit 6 of LCD
power control register) to “1”, apply the voltage value shown in
Table 12 according to the bias value. In this case, SEG22 pin and
SEG23 pin cannot be used.
Select a bias value by the bias control bit (bit 2 of the LCD mode
register).
Note: VLCD is the maximum value of supplied voltage for the
LCD panel.
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 reset is released, VCC
voltage is output from the common pin.
Note: Unused common pin outputs the unselected waveform.
Segment Signal Output Pin
The segment signal output pins (SEG0
SEG23) are shared with
ports P0
P2. When these pins are used as the segment signal
output pins, set the direction registers of the corresponding pins
to “1”, and set the segment output disable register to “0”.
Also, these pins are set to the input port after reset, the VCC
voltage is output by the pull-up resistor.
