Clear FCCU_NCF_Sx Issue

[liujinhang]

Hi:

     why doesn't the FCCU_NCF_Sx can be cleared by the following code ?

{

  FCCU.NCFK.R = FCCU_NCFK_KEY;

  FCCU.CTRL.B.OPR = 0xC;

  while(FCCU.CTRL.B.OPS != 0x3);

}

Thanks

You can use following code that cleat all faults (you can modify it to clear only some faults):

void ClearNCF(void)

{

    uint32_t i;

    for(i=0;i<4;i++)

    {

        FCCU.NCFK.R = FCCU_NCFK_KEY;

        FCCU.NCF_S[i].R = 0xFFFFFFFF;

        while(FCCU.CTRL.B.OPS != 0x3)

        {

        };              /* wait for the completion of the operation */

    }

}
