Trying to bit bang ADS7953

I'm trying to bit bang a 7953 16 channel, 12 bit converter.  It appears to be talking but the data doesn't make sense.

Code...

#define ADS7953_CLK  PIN_B1   //Clock
#define ADS7953_DOUT PIN_D4   //Data from Chip
#define ADS7953_CS   PIN_D5   //Chip Select
#define ADS7953_DIN  PIN_A2   //must change  Data to Chip

//Base routines
void write_ADS7953(int16 data) //Sends 16 bits of data
{
   int i;

   output_low(ADS7953_CLK);    //Initial State 
   output_low(ADS7953_CS);
   delay_us(1);
  
   output_high(ADS7953_CS);    //CS High for two clock cycles

   for(i=0;i<=2;i++)           //Toggle Clk twice,lo to hi
   {
      output_high(ADS7953_CLK);
      delay_us(1);
      output_low(ADS7953_CLK);
      delay_us(1);
   }

   output_low(ADS7953_CS);    //clk low, now CS low

   //start shifting data in
   for(i=1;i<=16;++i)
   {
      output_high(ADS7953_CLK);
      delay_us(1);
      output_bit(ADS7953_DIN, shift_left(&data,2,0));
      delay_us(1);
      output_low(ADS7953_CLK);
   }
   output_high(ADS7953_CS);   //End serial
}

//Base routines
long read_ADS7953()  //Gets 16 bits of data
{
   int i;
   long data;
   int8 chan;

   data=0;
   chan= 0;
  
   output_low(ADS7953_DIN);   //All Zeros - Doesn't matter in Auto Mode
  
   output_low(ADS7953_CLK);   //Initial States
   output_low(ADS7953_CS);
   delay_us(1);
  
   output_high(ADS7953_CS);  //CS high for 2 clk cycles

   for(i=0;i<=2;i++)             //toggle clk twice, lo to hi
   {
      output_high(ADS7953_CLK);
      delay_us(1);
      output_low(ADS7953_CLK);
      delay_us(1);
   }

   output_low(ADS7953_CS);       //make CS low

   for(i=0;i<12;++i) {           // shift 12 data bits from ADC
      output_high(ADS7953_CLK);
      delay_us(1);
      shift_left(&data,2,input(ADS7953_DOUT));
      output_low(ADS7953_CLK);
      delay_us(1);
   }

   for(i=0;i<4;++i) {           // shift 4 channel number bits from ADC
      output_high(ADS7953_CLK);
      delay_us(1);
      shift_left(&chan,1,input(ADS7953_DOUT));
      output_low(ADS7953_CLK);
      delay_us(1);
   }

   output_high(ADS7953_CS);
   printf("Channel: %d \r\n",Chan);
  
   return(data);
}

//0 = Manual
//1 = Auto1
//2 = Auto2
