TMS320C6678: DNUM是在哪里定义的？

static inline Uint32 KeyStone_Get_DSP_Number()
{
	TDSP_Board_Type DSP_Board_Type= KeyStone_Get_dsp_board_type();

	printf("DSP_Board_Type:%d, DNUM=%d\n", DSP_Board_Type, DNUM);

	if(DUAL_NYQUIST_EVM==DSP_Board_Type)
	{
		/*Nyquist EVM use boot configure pin 4 and 5 to identify DSPs*/
		return (( gpBootCfgRegs->BOOT_REG0 >> (3+1) ) & 0x03);
	}

	/*if use DNUM to differentiate DSPs for two DSPs test,
	the program must be run on core 0 of DSP 0 and core 1 of DSP1*/
	return DNUM;
