I am having problem to read and write to CLRC663 registers using SPI interface.

for example I need to write the value 0x98 to the T0control register (0Fh), I am sending the following data (address shifted with the LSB=0) (address, value)= (0x1E, 0x98)

and I tried to read it back by sending on MOSI (address shifted with the LSB=1), (addresss, 0x00)=(0x1F, 0x00), and I got every time defferent value which is not equal to (0x98): 

What do you think is the problem ? 

Please assist

Thank you
