我现在用STM8L152直接驱动LCD屏，出现一直显示的问题，无法清除掉，请大伙帮忙看看，谢谢！
/*IO口初始化*/
PA_DDR = 0xff;
PA_CR1 = 0x8f;//PA4,PA5,PA6对应COM0,COM1,COM2 ，PA7对应SEG0设为推挽输出
PD_DDR = 0xff;
PD_CR1 = 0xfd;//PD1对应COM3 COM口都设为开漏输出
PE_DDR = 0xff;
PE_CR1 = 0xff;//PE0~PE7对应SEG1~SEG8 推挽输出
/*LCD初始化*/
CLK_PeripheralClockConfig(CLK_Peripheral_LCD, ENABLE);
CLK_PeripheralClockConfig(CLK_Peripheral_RTC, ENABLE);//使能RTC时钟
CLK_RTCClockConfig(CLK_RTCCLKSource_HSI, CLK_RTCCLKDiv_16); //RTCCLK = 16MHz /16 = 1MHz
LCD_Init(LCD_Prescaler_32, LCD_Divider_26, LCD_Duty_1_8,LCD_Bias_1_4, LCD_VoltageSource_External);
LCD_PortMaskConfig(LCD_PortMaskRegister_0, 0xFF);//SEG0 ~ SEG7
LCD_PortMaskConfig(LCD_PortMaskRegister_1, 0x1F);//Unused pins as general purpose I/Os
