BT1-0:
When SW = 1, it switches the output of V5OUT between single, double, and triple boost. The
liquid crystal display drive voltage level can be selected according to its drive duty ratio and bias. A lower
amplification of the booster consumes less current.
BS2-0:
When SW = 1, it sets the crystal display drive bias value within the range of 1/4 to 1/6.5 bias. The
liquid crystal display drive bias value can be selected according to its drive duty ratio and voltage. For
details, see the Liquid Crystal Display Drive Bias Selector Circuit section.
