How to use AD7998 with BeagleBone

Hi,

this is what I don't understand. I have this commando "i2cset -y 1 0x22 Y_ X_"

1: BB-I2C-1 Bus

0x22: ADC-address

Y_: which register to write

X_: value

I want to need V_in_1. For my project I also need the GPIOs for the start conversion signal and Buzy flag. But in "Mode 2" there is a possibility to use the ADC without conversion signal.For example I want to use adress pointer byte for Vin1: 1 0 0 0   0 0 0 0 == HEX 0x80.

I tried this:

>root@beaglebone:/# i2cset -y  1 0x22 0x80

>root@beaglebone:/# i2cget -y  1 0x22 0x80

result > 0x07

But I am not sure if this is the right.
