At the end I managed to realize it... Very Happy
I'm using a 4 wire bus, with CS.

Code:

#include<Header.h>
#device *=16
#use delay(clock=16000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#define SDI    PIN_B4
#define SDO  PIN_C5      // the pin description is PIC oriented
#define SCKL PIN_C3
#define CNV  PIN_A4
#define LED  PIN_B2
int32 data=0;

int i;

void main()
{
unsigned long cnt=0;

while(1)
{
   output_high(SDO);                  
    output_high(CNV);         /* Starting conversion */
   output_low(SDO);                  
    delay_us(15);
                        /* Conversion Ended */

   for(i=19;i>0;--i)
//   for(i=32;i>13;--i)
               {   
               output_low(SCKL);
               output_high(SCKL);
               shift_left(&data,3,input(SDI));  /* maybe 1 instead of 3???*/
            //   bit_set(data, i)
            //   this function is too slow to be used in the application...
               }

   output_high(SDO);                  
   output_low(CNV);

   cnt ++;
   if (cnt==10000)
   {   
//      printf("\r the acquired value is: %x", data);
      printf("%x", data);
      data=0;
      output_toggle(LED);      /* Blinking LED for debugging*/
      cnt=0;
   }



} ;      



} // main() END


I will happy if anybody of u has comments/suggestions...
