TMS320F28374S: ADC采样ADCRESULTx 寄存器的值和实际对不上

ePWM_SOC触发ADC采样，但是ADCRESULTx 寄存器的值和实际对不上，比如实际是0V 显示却是4096，实际是3.3V显示是0，还有给一个引脚高电平，另一个同道的值反而会变、或者同时两路结果都变化的情况。

我使用的Sysconfig配置，下面是我的配置代码：

void Board_init()
{
EALLOW;

PinMux_init();
SYSCTL_init();
SYNC_init();
ADC_init();
EPWM_init();
GPIO_init();

EDIS;
}

void ADC_A_init(){
//
// Configures the analog-to-digital converter module prescaler.
//
ADC_setPrescaler(ADC_A_BASE, ADC_CLK_DIV_4_0);
//
// Configures the analog-to-digital converter resolution and signal mode.
//
ADC_setMode(ADC_A_BASE, ADC_RESOLUTION_12BIT, ADC_MODE_SINGLE_ENDED);
//
// Sets the timing of the end-of-conversion pulse
//
ADC_setInterruptPulseMode(ADC_A_BASE, ADC_PULSE_END_OF_ACQ_WIN);
//
// Powers up the analog-to-digital converter core.
//
ADC_enableConverter(ADC_A_BASE);
//
// Delay for 1ms to allow ADC time to power up
//
DEVICE_DELAY_US(500);
//
// SOC Configuration: Setup ADC EPWM channel and trigger settings
//
// Disables SOC burst mode.
//
ADC_disableBurstMode(ADC_A_BASE);
//

//

//
ADC_setupSOC(ADC_A_BASE, ADC_SOC_NUMBER0, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN0, 16U);
ADC_setInterruptSOCTrigger(ADC_A_BASE, ADC_SOC_NUMBER0, ADC_INT_SOC_TRIGGER_NONE);
//

ADC_setupSOC(ADC_A_BASE, ADC_SOC_NUMBER1, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN1, 16U);
ADC_setInterruptSOCTrigger(ADC_A_BASE, ADC_SOC_NUMBER1, ADC_INT_SOC_TRIGGER_NONE);

ADC_setupSOC(ADC_A_BASE, ADC_SOC_NUMBER2, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN2, 16U);
ADC_setInterruptSOCTrigger(ADC_A_BASE, ADC_SOC_NUMBER2, ADC_INT_SOC_TRIGGER_NONE);
//

//
//

ADC_setupSOC(ADC_A_BASE, ADC_SOC_NUMBER3, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN3, 16U);
ADC_setInterruptSOCTrigger(ADC_A_BASE, ADC_SOC_NUMBER3, ADC_INT_SOC_TRIGGER_NONE);
