TMS320F2812 SCI PROBLEM

Hi, I am having some problem wit sci communication. I have the following problem, i am sending values by sci, in a loop. And the first bytes are dummy values (incorrect  information) but then it is working well.

I dont know why the first bytes are incorrect.

I really apreciate your help.

All of configuration registers are correctly configured.

 	SciaRegs.SCICCR.all =0x0007;   
	SciaRegs.SCICTL1.all =0x0003; 
	SciaRegs.SCICTL2.all =0x0000; 
	SciaRegs.SCIHBAUD    =0x0000;
     SciaRegs.SCILBAUD    =0x0003;
	SciaRegs.SCICCR.bit.LOOPBKENA =0; // Enable loop back  
	SciaRegs.SCICTL1.all =0x0023;     // Relinquish SCI from Reset 

 SciaRegs.SCIFFTX.all=0xE040;
     SciaRegs.SCIFFRX.all=0x204f;
     SciaRegs.SCIFFCT.all=0x0;

I am not using interrupts

This is my code

void average(void)
{
Uint16 fila=0,i=0;
     
		   for(i=0;i<9;i++)
				{
			     
                  resultado=mat_datos[0][i];
		          scia_xmit();
			        }
        
}

void scia_xmit()
{
  	for(ind=2;ind>=0;ind--)
	   {
   
	  sendchar=((resultado >> (ind*8)) & 0x000000FF);
	   SciaRegs.SCITXBUF=sendchar;
	  while(SciaRegs.SCIFFTX.bit.TXFFST > 0 ){}                               
      
	   }

   resultado=0;
}
