Hello, to all

I am configuring the DMA parameter regisrters likeis below, and i wnat to see in the simulator of Visual DSP5.0 ++ the contens of the register. In menu Register/ I/O / DMA addressing. But there in II register are only zeros. Is that correc ot not. Cause there have to be the address of the rx_buf0amassif - it doesn`r show!!!!

 

void Init_DMA_Sport(void)
{

// initially clear SPORT control register
* (volatile int *) SPCTL0 = 0;
* (volatile int *) SPCTL1 = 0;

//SPORT_DMA_setup:
   
*pIISP0A = rx_buf0a[0]; 
*pIMSP0A = 1;     
*pCSP0A = sizeof(rx_buf0a);


*pIISP1A = tx_buf1a[0]; 
*pIMSP1A = 1;     
*pCSP1A = sizeof(tx_buf1a);

 

}
