6.2.5.6 ClearFSMStatus

The ClearFSMStatus() function is responsible for clearing the status of the previous flash operation.

Fapi_FlashStatusType  oFlashStatus;
Fapi_StatusType  oReturnCheck;

while (Fapi_checkFsmForReady(u32StartAddress, u32UserFlashConfig) != Fapi_Status_FsmReady){}
oFlashStatus = Fapi_getFsmStatus(u32StartAddress, u32UserFlashConfig);


oReturnCheck = Fapi_issueAsyncCommand(u32StartAddress, u32UserFlashConfig, Fapi_ClearStatus);
while (Fapi_getFsmStatus(u32StartAddress, u32UserFlashConfig) != 0);

if(oReturnCheck != Fapi_Status_Success)
{
    Sample_Error();
}
