DCO setting with respect ot BCL12

Hi,

I a little bit confused after reading BCL12 case.  Is there any thing wrong with the following code when we consider BCL12, or any other things about updating DCO? 

//---------------------------------------

static int clock_set_dco(const uint8 calbc1_x, const uint8 caldco_x)

{
   static int powerup = 0;

   if (calbc1_x == 0xFF)
   {
      return 0; //FAILURE
   }

   if(powerup == 0)
   {
      __delay_cycles(100000);

      DCOCTL = 0x00;
      BCSCTL1 = calbc1_x;
      DCOCTL = caldco_x;

      powerup = 1;
   }
   else
   {
      if( (BCSCTL1 & 0x0F) > 0x0D )
         BCSCTL1 = 0x8D;

      BCSCTL1 = 0x87;

      DCOCTL = caldco_x;

      if( (calbc1_x & 0x0F) > 0x0D)
         BCSCTL1 = 0x8D;

      BCSCTL1 = calbc1_x;
   }

   return 1; //SUCCESS
}

//---------------------------

Thank you for your reply
