Problems with SPI and ADS8320

Hi Jeremy! Hi everyone!
I tried seting the spi delay to 1 as you told me and now I see the correct 
behaviour. The problem now is that I can read only 10 bits of the 16 the ADC 
returns.
As I see from the oscilloscope after 10 bits chip select signal goes high and 
low causing the ADS8320 to restart bitstream transmission. What can I do to 
read all of the 16 bits? 
I tried to change the array length but this causes an arrayindexoutofbounds 
exception...

Here is spi initialization:

spi = new SPI(1, true, true, false, false, false, false, true);

Here is the source code that performs conversion:

...

void convertAtoD(double samples) {

	System.out.println("Performing conversion...");

        byte[] spidata = new byte[4];

	for(int i=0; i<4; i++)
	{
		spidata[i] = (byte) 0x00;
	}

        spi.xmit(spidata, 0, spidata.length);

	System.out.println();
	System.out.println("Array dimension: " + spidata.length);

        for(int i=0; i<4; i++)
        {
	        System.out.print("Bitstream: ");
		printBinary(spidata[i]);
	}
          
	System.out.println();
	System.out.println("Completed.");

}


private static void printBinary(byte b) { 
        for (int val = 7; val >= 0; val--) 
        { 
                System.out.print((b >> val) & 1); 
        } 
 
        System.out.println(); 
} 

...

Thanks a lot for the support!

Best regards,
