 void adcStartConversion(adcBASE_t *adc, uint32 group)
{
/* USER CODE BEGIN (7) */
/* USER CODE END */

    /** - Setup FiFo size */
    adc->GxINTCR[group] = s_adcFiFoSize[0U][group];

    /** - Start Conversion */
    adc->GxSEL[group] = s_adcSelect[0U][group];

这段代码我还看得懂但是后面进入= s_adcSelect[0U][group];我就看晕了
static const uint32 s_adcSelect[1U][3U] =

这些代码是在做什么，我还没有系统学习单片机，正在STM32和570对照着学，求解。谢谢
