6.2.14 ClearFSMStatus

The ClearFSMStatus() function is responsible for clearing the status of the previous flash operation. This function is applicable for F280013x, F280015x, F28P65x and F28P55x devices. This function must be used as-is.

Fapi_FlashStatusType  oFlashStatus;
Fapi_StatusType  oReturnCheck;

// Wait until FSM is done with the previous flash operation
while (Fapi_checkFsmForReady() != Fapi_Status_FsmReady){}

oFlashStatus = Fapi_getFsmStatus();

if(oFlashStatus != 0)
{

    /* Clear the Status register */
    oReturnCheck = Fapi_issueAsyncCommand(Fapi_ClearStatus);

    // Wait until status is cleared
    while (Fapi_getFsmStatus() != 0) {}

    if(oReturnCheck != Fapi_Status_Success)
    {
        // Check Flash API documentation for possible errors
        Sample_Error();
    }
}
