Segments S0 through S3 are disabled when the LCD charge pump feature is enabled (LCDCPEN = 1) and, therefore, cannot be used
together with the LCD charge pump. On the MSP430xG461x devices only, S0 through S3 are also disabled if VLCDEXT = 1. This
setting is typically used to apply an external LCD voltage supply to the LCDCAP terminal. For these devices, set LCDCPEN = 0,
VLCDEXT = 0, and VLCDx > 0 to enable an external LCD voltage supply to be applied to the LCDCAP terminal.
