MSP430FR6972: msp430fr6972的LCD功耗是多少大？

我这边使用的是MSP430FR6972芯片，我这边开启LCD的功耗运行功耗在30UA左右，直接关闭LCD功耗降到4-7个UA，请问是芯片LCD功耗是20多个UA吗？

还是说我我LCD配置的问题？

void InitLCD(void)    //LCD初始化
{
//P6SELC|= BIT0+BIT1+BIT2+BIT3 +BIT4 +BIT5+BIT6; // Enable COMx Pin

// Initialize LCD segments 0 - 14; 26 - 43
LCDCPCTL0 = 0x7FFF;
// LCDCPCTL1 = 0x0000;
// LCDCPCTL2 = 0x0000;

/* Sourcing the LCD from the crystal */
LCDCCTL0 = LCDDIV__1 | LCDPRE__16 | LCD4MUX | LCDLP;

// VLCD generated internally,
// V2-V4 generated internally, v5 to ground
// Set VLCD voltage to 2.60v
// Enable charge pump and select internal reference for it
LCDCVCTL = VLCD_1| VLCDREF_0 | LCDCPEN;

LCDCCPCTL = LCDCPCLKSYNC; // Clock synchronization enabled

LCDCMEMCTL = LCDCLRM; // Clear LCD memory

LCDCCTL0 |= LCDON;
}
