有沒會C8051F410的大神呢？我按照步驟設置電壓檢測，測得值一直上漲，求大神幫忙看下

/*ADC初始化*/

  ADC0TK = 0xF9;    //Pre-tracking mode  F8  3個 F9  4
}
/*引腳定義*/
void Port_IO_Init()
{
P0MDIN = 0xFD;       //P0.1 模擬輸入 MISO  0.5不能配置成模擬輸出，否則接收不到數據
P1MDIN = 0xFB;       //P1.2 Vref模擬輸入

P0MDOUT = 0x9D;       //P0.3,P0.4Tx,P0.7LYreset P0.0(SCK),P0.2(MOSI)推免輸出

P1SKIP = 0x07;    //X1,X2,Vref跳過
P2SKIP = 0x04;       //ADC跳過

XBR0    = 0x03;    //UART0連接到端口
XBR1    = 0x50;    //使能
}

EIE1  &=0xF7;                            //關閉ADC中斷
}
//測量電池電壓函數，主函數直接調用
void MeasurePower()
{
  EIE1 |= 0x08;             //開啟ADC中斷
  ADC0CN  = 0x00;             //AD0EN=0,低功耗模式，Buzy寫1啟動轉換
  AD0EN    =  1;                //使能ADC
  AddADCtemp =  0;
  ADCTimes =  0;
  AD0BUSY =  1;                //啟動一次轉換  Delay(1000);
  EIE1 |= 0x08;          //啟動ADC0轉換結束中斷
}

引腳不夠用了，定時器用了兩個，也沒相關參考程序，用的busy寫1中斷
