LCD Power Supply
The LCD power supply is equipped with voltage charge-pump, and bias voltage generating resistor
network. The input power VDD of MCU is charge-pumped to generate LV3. The voltage of LV3 may be
up to 1, 2 or 3 times of VDD depending on the external capacitor configurations and VDD connection.

The bias voltages for LCD driver are then generated from LV3 using the internally resistor voltage
dividing network if the mask option MO_LCDBE is set to ‘1’ and the resistance of bias voltage
generating network can be adjusted by mask option MO_LCDBS[2..0]. Users may select options with
smaller resistance to get stronger bias voltages as needed when driving larger LCD panel. However the
bias network will consume more power as consequence. Therefore uses must trade off between bias
