用430fg4618驱动段码式液晶，全部显示（所有显示寄存器都有内容）时闪屏，平时不闪，发现更换32768晶振有可能解决此问题，液晶屏初始化程序如下：
void LCD_A_init(LCD_A_initParam *initParam)
{

LCDACTL = initParam->clockDivider | initParam->muxRate |LCDSON;
LCDAPCTL0 = LCDS0 + LCDS4 + LCDS8 + LCDS12 + LCDS16 + LCDS20 + LCDS24 + LCDS28;
LCDAPCTL1 = LCDS32 + LCDS36;
LCDAVCTL0 = initParam->bias;
LCDAVCTL1 = 0;

LCD_A_clearAllMemery();
LCD_A_on();
}

void LCD_SEG_init()
{
GPIO_setAsPeripheralModuleFunctionPin(LCD_A_COM1);
GPIO_setAsPeripheralModuleFunctionPin(LCD_A_COM2);
GPIO_setAsPeripheralModuleFunctionPin(LCD_A_COM3);

//lcd_a init
LCD_A_initParam LCD_A_initParameter;
LCD_A_initParameter.clockDivider = LCD_A_CLOCKDIVIDED_32;
LCD_A_initParameter.muxRate = LCD_A_4_MUX;
LCD_A_initParameter.bias = LCD_A_BIAS_1_3;
LCD_A_init(&LCD_A_initParameter);
}
