Read operation in AD569x

Hello,

 

I've read the i2c read operation chapter in:

 

http://www.analog.com/media/en/technical-documentation/data-sheets/AD5693R_5692R_5691R_5693.pdf 

 

Yet, I'm still not sure how the read operation should be done:

1. What is the command byte for a read operation, i.e. can it be any register from table 12 ? Seems that table 12 only lists the write command ? for example, can I read "control register" (in table it is described is write control register) ?

2. In diagram of read operation it shows the following bytes:

     slave address, control command, high data byte. What about the low data byte ?

 

 

Thank you,

ranran
