pump the 2.25 volts to 9 volts requires 4 times multiplier; to pump the 3 volts to 9 volts requires only 3
time multiplier which consumes less power. So it is advisable not to adjust the LVREG to an unnecessary
low level.
Voltage multiplication:
The LVREG is then multiplied by 3, 4, or 5 times, depending on external
capacitors configurations as shown below, to generate LVP. Please note that LVP must be lower than 9
volts to prevent chip from breaking down.

The LVP is then regulated to generated LVL1 ~ LVL5. LVL5 can be adjusted by the resistor between
LGS2 and LV5. Be sure to leave at least 0.3 volt between LVP and LV5 for the regulator circuit to
function properly. The formula is:
LVL5 = (1 + R2/80K) x 0.9V
Different duties require different bias settings. There is some theoretical correspondence between the
Duty and Bias Setting. However, it is better to use it as starting point and adjust it with real LCD panel
connected to it to determine the final setting. The theoretic relationship between the duty and bias setting
as following:
Duty Cycle Normal Bias Alternative Bias
32 duty
1/7
48 duty
1/8
64 duty
1/9
80 duty
1/10
1/7.5
1/7.5, 1/8.5
1/8.5, 1/9.5
1/9.5, 1/10.5
The bias setting is made by mask option MO_LBSR[2..0].
MO_LBSR[2..0] Bias Setting
