ADS8684: using TM24C19X processor with ADS8684 Data acquisition question

Part Number: ADS8684

I have design a board using the TM24C19X. after power the board up (default setting for the ADS8684)  I follow the manual data acquisition steps as per spec (pg 84) toggle CS between events .

1) write MAN_ch1 (32 clock cycles) read sample N from previous conversion 

2) Write NOP (000) 32 cycles to retrieve the converted channel  1

I have to add an addition write NOP to get the converted data - data is right though

Question: why do I have to do the addition NOP write and two spec pg 34 (data acquisition example) seems to imply I can do it in one 32 clock cycles. 

is there a simple code splice (not the Linux version) for this chip?
