TM4C129ENCPDT: Analog to digital conversion delay when using ADC sequencer

Hi

I am acquiring the data from 8 analog inputs, using to sequencers (Sequence Number 1), using the 2 ADCs of the TM4C MCU. I know that both ADC can read simultaneously but the sequence means a delay when reading two analog inputs with the same ADC, how can i know what is the value of this delay  if I am using a timer to control de acquisition? The sampling frequency (Fs) is 200 KHz. Here is the ADC configuration of both ADCs:

void ADCconfigure(uint32_t sysclock ,uint32_t Fs)

{
    SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC0);
    SysCtlPeripheralSleepEnable(SYSCTL_PERIPH_ADC0);
    ADCClockConfigSet(ADC0_BASE,ADC_CLOCK_SRC_PIOSC | ADC_CLOCK_RATE_FULL, 1);

    ADCSequenceConfigure(ADC0_BASE, 1, ADC_TRIGGER_TIMER, 0);
    ADCSequenceStepConfigure(ADC0_BASE, 1, 0, ADC_CTL_CH16/*PK0*/);
    ADCSequenceStepConfigure(ADC0_BASE, 1, 1, ADC_CTL_CH17/*PK1*/);
    ADCSequenceStepConfigure(ADC0_BASE, 1, 2, ADC_CTL_CH18/*PK2*/);
    ADCSequenceStepConfigure(ADC0_BASE, 1, 3, ADC_CTL_CH19/*PK3*/ | ADC_CTL_END | ADC_CTL_IE);
    ADCSequenceDMAEnable(ADC0_BASE, 1);
