I need to connect external ACD, AD7680 and LPC1343with SPI line

in examples of SPI, there is only examples of Master send and Slave receive, but I need Master to receive

with current configuration, I think that clock is 0.5MHz, can someone confirm this ?

AD7680 sends 24bits, of that 16 bits of information
my intention was to set FIFO frames to 4-bit transfer, and from 4 frames get information
problem is that in current code, I don't get anything on line SCK when viewing on digital oscilloscope

help, please!!

at least point me to some web places where to find some information

thnx in advance
