The built-in LCD power supply is equipped with input voltage regulator, voltage multiplier and bias
voltage generating circuit with active buffer instead of passive resistor voltage dividing network. If the
external LCD power is provided, the internal LCD power system shall be disabled. The following table
shows the relationship of the LCD power system
LCDE(LCDC BIT0)
MO_PSMODE[1:0]
Function
1
00
Internal voltage multiplier and Bias voltage
generating circuit are enable to supply the
LCD display power.
1
01
Internal voltage multiplier is enabled, but the
Bias voltage generating circuit is disabled,and
the external power sources are applied
LV4~LV1.
1
10
Internal voltage multiplier is disabled, but the
Bias voltage generating circuit is enabled.
The single external power is applied to LV5,
and internal bias circuit will generate the
LV4~LV1 voltages.
1
11
Internal voltage multiplier and Bias voltage
generating circuit are disabled, and the
external power sources are applied to
LV5~LV1.
0
00
The lcd power system is disable,but the LV5~
LV1 is applied to VDD .
0
01
The lcd power system is disable,but the LV5
is applied to VDD and LV4~LV1 is applied to
hight impedance.
0
10
The lcd power system is disable, LV5 is
applied to hight impedance,and the LV4~LV1
Applied to LV5.
0
11
The lcd power system is disable, LV5~LV1 is
applied to hight impedance.
