(1)
Refer to the supply current specifications I
(LPM3)
for additional current specifications with the LCD_A module active.
(2)
Connecting an actual display increases the current consumption depending on the size of the LCD.
(3)
Enabling the internal charge pump with an external capacitor smaller than the minimum specified might damage the device.
(4)
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.
