We are using MC50XS4200BEK for load driving. Reading of the register contents is not working as per data sheet. First we write SI STATR register which contains address of the SO register. Then generating 16 clock pulses by sending same word. During second cycle the expected word is the required SO register. But, actually getting the SI STATR register as we write it previously. The observation is whatever the register we write previously is shifting out in the next cycle, irrespective of SI STATR contents.
