TMS570LS1114: Can the VIM parity diagnostic interface be called periodically?

Part Number: TMS570LS1114

When I call the SL_SelfTest_VIM (SL_SelfTestType testType) interface, the input parameter is set to VIM_SRAM_PARITY_TEST. Then, in the while(1) loop, I call this interface periodically to diagnose VIM periodically. However, after running for a period of time, there will be a diagnosis failure error, because the diagnosis interface cannot be called periodically, or can only be power-on diagnosis?

As shown below, the if condition in the red box is entered,The registers sl_vimParREG->PARFLG and sl_esmREG->SR1[0U] are both 0.

Please answer the above questions, thank you.
