Drive Power Select
Triple Step-up Voltage Circuit Control
The triple step-up voltage circuit stops operation when
Vcc is selected as drive power. The triple step-up voltage
circuit starts operation when LCD input reference voltage
(V
0: Drive power is Vcc, triple step-up voltage circuit halts
1: Drive power is triple step-up voltage of the LCD input

Selection of Duty Ratio for Charge/Discharge Pulse
Duty ratio is selected during the power supply divider
resistance is connected to power supply circuit. When the
duty ratio of 0 is selected, the power supply divider
resistance is fixed to the state that the resistance is
separated from the power supply circuit. Therefore,
supply the power to pins V
circuit.
The charge/discharge pulses have the waveform shown
in figure 17.2. The duty ratio is represented by T
0000: duty ratio = 1 (stack at high)
0001: duty ratio = 1/8
0010: duty ratio = 2/8
0011: duty ratio = 3/8
0100: duty ratio = 4/8
0101: duty ratio = 5/8
0110: duty ratio = 6/8
0111: duty ratio = 0 (stack at low)
10XX: duty ratio = 1/16
11XX: duty ratio = 1/32
