Hi,
   I am interfacing an AD Converter with MPC566, and written code for 
QSPI in C using CodeWarrior compiler 8.1. I am trying to read a 
register called as 'channel conversion time register'(of ADC) by 
sending its address to the 'communication register'(of ADC). The 8 
bit register address of the 'channel conversion time register' has to 
be set in 6 bit of 'communication register'. But while executing 
QSPI,in Receive RAM,it shows 'FFFF'. How do I know, whether I am able 
to write anything on this 'communication register' or not.
Can anyone please suggest something on this? 

Following are the specifications of ADC:
4-channle, +/-10 input range, 24-bit ADC (AD7734 from analog devices).

-Regards
Rajesh
