This pin can be either an analog input when the LCD resistor driver is enabled or an analog output when
the LCD charge pump is enabled. When this pin is an analog output, it should be decoupled with a 470 nF
capacitor. When this pin is an analog input, it is internally connected to V
between this pin and LCDVB to generate the two highest voltages for the LCD waveforms (see the LCD
Driver section).
This pin can be either an analog input when the LCD resistor driver is enabled or an analog output when
the LCD charge pump is enabled. When this pin is an analog output, a 100 nF capacitor should be connected
between this pin and LCDVP1. When this pin is an analog input, it is internally connected to LCDVP1 (see the
LCD Driver section).
This pin can be either an analog input when the LCD resistor driver is enabled or an analog output when
the LCD charge pump is enabled. When this pin is an analog output, it should be decoupled with a 470 nF
capacitor. When this pin is an analog input, a resistor should be connected between this pin and LCDVC to
generate an intermediate voltage for the LCD driver. In 1/3 bias LCD mode, another resistor must be
connected between this pin and LCDVA to generate another intermediate voltage. In 1/2 bias LCD mode,
LCDVB and LCDVA are internally connected (see the LCD Driver section).
