Chapter 9 Liquid Crystal Display Driver (S08LCDV1)
9.2.6
The charge pump capacitor is used to transfer charge from the input supply to the regulated output. It is
recommended that a low equivalent series resistance (ESR) capacitor be used. Proper orientation is
imperative when using a polarized capacitor.
9.3
This section consists of register descriptions. Each description includes a standard register diagram.
Details of register bit and field function follow the register diagrams, in bit order.
9.3.1
Read: anytime
Write: LCDEN anytime. To avoid segment flicker the clock prescaler bits (LCLK[2:0]) and the duty select
bits (DUTY[1:0]) must not be changed when the LCD module is enabled.
