MSP432P401R: MSP432 ADC14 Multiple Channel only converts one value in the sequence.

Part Number: MSP432P401R

Hi,

I am running into the an issue where the ADC is set for multi sequence mode, but only performs a reading for ADC_MEM0 and leaves the other ones unchanged. I am checking the issue by setting up ADC_MEM0 , ADC_MEM1 and ADC_MEM2 to the same analog input to see if i get the same results. the analog input has a 3.3V input connected to it and I am using the 14 bit conversion for the ADC. I send the results to a terminal over serial and I see the following:

ADC_MEM0 = 16383
ADC_MEM1 = 3488
ADC_MEM2 = 5576

However, they should be the same. Also, if I change the voltage, ADC_MEM1 and ADC_MEM2 do not change their respective value. My code is below. I use a main loop to call the MAP_ADC14_toggleConversionTrigger function. Do you have any suggestions?

void init_ADC_no_temp(void)
{
   
      /* Setting reference voltage to 2.5 and enabling temperature sensor */

        MAP_REF_A_setReferenceVoltage(REF_A_VREF2_5V);
        MAP_REF_A_enableReferenceVoltage();

      /* Initializing ADC (MCLK/1/1) with temperature sensor routed */
      MAP_ADC14_enableModule();
      MAP_ADC14_initModule(ADC_CLOCKSOURCE_MCLK, ADC_PREDIVIDER_1, ADC_DIVIDER_1, 0);

      /* Setting up GPIO pins as analog inputs (and references) */
       MAP_GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P4,
       GPIO_PIN7 | GPIO_PIN5, GPIO_TERTIARY_MODULE_FUNCTION);

      /* Configuring ADC Memory   */
      MAP_ADC14_configureMultiSequenceMode(ADC_MEM0, ADC_MEM2, false);

      MAP_ADC14_configureConversionMemory(ADC_MEM0, ADC_VREFPOS_INTBUF_VREFNEG_VSS, ,
          ADC_INPUT_A6, ADC_NONDIFFERENTIAL_INPUTS);
      MAP_ADC14_configureConversionMemory(ADC_MEM1, ADC_VREFPOS_INTBUF_VREFNEG_VSS,
          ADC_INPUT_A6, ADC_NONDIFFERENTIAL_INPUTS); 
      MAP_ADC14_configureConversionMemory(ADC_MEM2, ADC_VREFPOS_INTBUF_VREFNEG_VSS,
          ADC_INPUT_A6, ADC_NONDIFFERENTIAL_INPUTS); 

      /* Configuring the sample/hold time for 192 */
      MAP_ADC14_setSampleHoldTime(ADC_PULSE_WIDTH_192,ADC_PULSE_WIDTH_192);

      MAP_ADC14_enableInterrupt(ADC_INT2);

      /* Enabling Interrupts */
        MAP_Interrupt_enableInterrupt(INT_ADC14);
        MAP_Interrupt_enableMaster();

      MAP_ADC14_enableSampleTimer(ADC_AUTOMATIC_ITERATION);

      /* Triggering the start of the sample */
          MAP_ADC14_enableConversion();
          MAP_ADC14_toggleConversionTrigger();
}

void ADC14_IRQHandler(void)
{
    uint64_t status;
    char strToSendLocal[200]= "";
	uint16_t resultsBuffer[3];
    status = MAP_ADC14_getEnabledInterruptStatus();
    MAP_ADC14_clearInterruptFlag(status);
    
    if(status & ADC_INT2)
    {      
        MAP_ADC14_getMultiSequenceResult(resultsBuffer);
       //MAP_ADC14_getResultArray(ADC_MEM0, ADC_MEM2, resultsBuffer);
        sprintf(strToSendLocal, "All raw values: %i, %i, %i",resultsBuffer[0],resultsBuffer[1], resultsBuffer[2]);
        sendStringToUART_A2(strToSendLocal, sizeof(strToSendLocal)); //Send message to UART2

    }
