Power Control
BS2D0:
The LCD drive bias value is set within the range of a 1/4 to 1/11 bias. The LCD drive bias value
can be selected according to its drive duty ratio and voltage. For details, see the Liquid Crystal Display
Drive Bias Selector section.
BT1-0:
The output factor of V5OUT between two-times, three-times, four-times, five-times, six-times, and
seven-times boost is switched. The LCD drive voltage level can be selected according to its drive duty ratio
and bias. Lower amplification of the booster consumes less current.
DC1-0:
The operating frequency in the booster is selected. When the boosting operating frequency is high,
the driving ability of the booster and the display quality become high, but the current consumption is
increased. Adjust the frequency considering the display quality and the current consumption.
AP1-0:
The amount of fixed current from the fixed current source in the operational amplifier for V pins
(V1 to V5) is adjusted. When the amount of fixed current is large, the driving ability of the booster and the
display quality become high, but the current consumption is increased. Adjust the fixed current considering
the display quality and the current consumption.
During no display, when AP1D0 = 00, the current consumption can be reduced by ending the operational
amplifier and booster operation.
