想請教各位先進，如果想使用timer trigger soc 後 觸發EOC 發生 ADC interrupt，timer有需要做什麼特別設定嗎?

目前我是使用timer1 觸發SOC

ADC.c 是這樣設定的
    AdcRegs.ADCCTL1.bit.INTPULSEPOS = 1;     // ADCINT trips after AdcResults latch
    AdcRegs.INTSEL1N2.bit.INT1CONT = 0;
    AdcRegs.INTSEL1N2.bit.INT1E = 1;
    AdcRegs.INTSEL1N2.bit.INT1SEL = 2;         // EOC2 is Trigger for ADCINT1
  
    AdcRegs.ADCSOC0CTL.bit.CHSEL = 0x02;     // ADCINA2
    AdcRegs.ADCSOC0CTL.bit.TRIGSEL = 2;     //Timer1 trigger soc
    AdcRegs.ADCSOC0CTL.bit.ACQPS = 8;

Timer1 的設定如下:

void Init_Timer1(void)
{
    EALLOW;
    // Initialize timer period to maximum
    CpuTimer1Regs.PRD.all = 0xFFFFFFFF;

    // Initialize pre-scale counter to divide by 500 (SYSCLKOUT)
    // Cpu timer dived-down every(TDDRH:TDDR+1) (1:F3+1 -> 1F4(500))
    CpuTimer1Regs.TPR.all = 0x00F4;
    CpuTimer1Regs.TPRH.all = 0x0001;

    // Initialize timer period
    CpuTimer1Regs.PRD.all = dTimer_PRD - 1;
    CpuTimer1Regs.PRD.all = D2D_PWR.Trigger_Point;
    // Initialize timer control register
    CpuTimer1Regs.TCR.bit.TSS = 1; // 1 = stop timer, 0 = Start / Restart Timer
    CpuTimer1Regs.TCR.bit.TRB = 1; // Reload timer counter to PRD
    CpuTimer1Regs.TCR.bit.SOFT = 1;
    CpuTimer1Regs.TCR.bit.FREE = 1; // Timer Free Run
    CpuTimer1Regs.TCR.bit.TIE = 1; // Enable Timer Interrupt
    EDIS;

}

但結果還是沒有去trigger soc 發生ADC中斷，謝謝各位的協助和回答!
