Compiler/MSP430F5419A: why this method returns me a unsigned char instead of unsigned short

Part Number: MSP430F5419A

Tool/software: TI C/C++ Compiler

i make a method that read the adress of a controller conected to msp430.

we put and object, this objects is one of those which are defined in the regiter memory of the controller.

the address i want to get it, has 16 bit so i need to return at least an unsigned int, because there are not signed address.

the method is this:

unsigned int TactilI2C::Get_Start_Position(unsigned char Element) 
{
  
    unsigned int Address = 0;
    
    for(int i = 0; i <  data.info.Num_Obj_Declarados; i++ )
    {
      if(data.object_table[i].Type == Element)
      {
         Address |= (data.object_table[i].MSB << 8);
         Address |= data.object_table[i].LSB;
         return Address;
      }
    }
    
    return Address;
    
}

when this function return, the value get it is a value like 0x005A when the correct value  is 0x045A.

i put the method had called the function:

int TactilI2C::Write_Object_Config(unsigned char Object_Type, mxt_config *cfg)
{
  
  unsigned char ucObj_Buf[256];
  unsigned char usObj_Addr[2];
  unsigned short usDevice_Size;
  unsigned short num_bytes;
  bool error = false;
 
  if (Object_Is_Volatile(Object_Type))
  {  
     return TACTI2C_ERROR_OBJECT_IS_VOLATILE; // object is volatile
  }
  
   usObj_Addr = Get_Start_Position(Object_Type); // here is called
   

  if (error){
    return error;
  }
  
  usDevice_Size = (unsigned short)Get_Object_Size(Object_Type);
  
  //compare if sizes are diferent read from device config and read from config file (in our case hardcode)
  if (usDevice_Size > cfg->objcfg.size) 
  {
    m_pLog->Traza (LOG_NIV_FINAL, MSGLOG_ERROR, "TactilI2C::Write_Object_Config() --->  Extending config by: "); 
    m_pLog->TrazaDirecto (LOG_NIV_MEDIO, (char*)(usDevice_Size - cfg->objcfg.size));
    m_pLog->Traza (LOG_NIV_FINAL, MSGLOG_ERROR, "TactilI2C::Write_Object_Config() --->   bytes in T:"); 
    m_pLog->TrazaDirecto (LOG_NIV_MEDIO, (char*)cfg->objcfg.type);
    
    num_bytes = cfg->objcfg.size;
  } 
  else if (cfg->objcfg.size > usDevice_Size) {
    
    /* Either we are in fallback mode due to wrong
    * config or config from a later fw version,
    * or the file is corrupt or hand-edited */
    m_pLog->Traza (LOG_NIV_FINAL, MSGLOG_MESSAGE, "TactilI2C::Write_Object_Config() --->  Discarding: "); 
    m_pLog->TrazaDirecto (LOG_NIV_MEDIO, (char*)cfg->objcfg.size - usDevice_Size);
    m_pLog->Traza (LOG_NIV_FINAL, MSGLOG_MESSAGE, "TactilI2C::Write_Object_Config() --->   bytes in T:"); 
    m_pLog->TrazaDirecto (LOG_NIV_MEDIO, (char*)cfg->objcfg.type);

    num_bytes = usDevice_Size;
  
  }else {
    
    num_bytes = usDevice_Size;
  
  }
                   
  /* Update bytes from config */
  memcpy(ucObj_Buf, cfg->objcfg.data, num_bytes);

  /* Write object */ 
  error = WriteRegister(usObj_Addr, ucObj_Buf, num_bytes);
  
  if (error)
  {
    m_pLog->Traza (LOG_NIV_FINAL, MSGLOG_ERROR, "TactilI2C::Write_Object_Config() ---> Config write error");
    return error;
  }
  
  return 0;
