MSP430F4619采用LCD_A电压泵功能后液晶S0-S8不显示

void LcdInit()

{

P5SEL = 0xFC;

LCDACTL = LCDON+LCD4MUX+LCDFREQ_128;

LCDAPCTL0 = 0xFF;

LCDAPCTL1 = 0x03;

// LCDAVCTL1 = VLCD_12;

// LCDAVCTL0 = LCDCPEN;

}

以上为初始化函数，不适用电压泵功能液晶一切正常。

当不注释两句电压泵相关配置寄存器后S0-S8不显示，其他都正常。

IO口配置应该也没啥问题，现在搞不懂了

寻求好心人帮助^-^

您可以看一下数据手册 第7页 MSP430x461x Terminal Functions

NOTE 1: Segments S0 through S3 are disabled when the LCD charge pump feature is enabled (LCDCPEN = 1) and cannot be used together with the LCD charge pump. In addition, when using segments S0 through S3 with an external LCD voltage supply, VLCD ≤ AVCC.
