_c_int00 中的 ESM group3有错误产生，esmREG->SR1[2] == 2 。请问这是什么错误？

_c_int00 

if ((esmREG->SR1[2]) != 0U)   //  esmREG->SR1[2] == 2, 进入下面的for。
{
/* USER CODE BEGIN (24) */
/* USER CODE END */
/*SAFETYMCUSW 5 C MR:NA <APPROVED> "for(;;) can be removed by adding "# if 0" and "# endif" in the user codes above and below" */
/*SAFETYMCUSW 26 S MR:NA <APPROVED> "for(;;) can be removed by adding "# if 0" and "# endif" in the user codes above and below" */
/*SAFETYMCUSW 28 D MR:NA <APPROVED> "for(;;) can be removed by adding "# if 0" and "# endif" in the user codes above and below" */
for(;;)
{
}/* Wait */

这是什么原因引起的？

谢谢
