Re Bistream Configuration: Frame bits to LUTs

Hi,

I was wondering if anyone could answer me with a question regarding bitstream configuration.

In virtex 5 user guide- https://www.xilinx.com/support/documentation/user_guides/ug191.pdf

page 130 mentions that 41 words (each 32bit) configure 20 CLBs, which would imply that for each CLB there are only 64 bits and for each slice there are 32 bits. How can 32bits configure 4 LUTs, FFs, etc.? You would need over 200bits.. Can anyone help with how LUT programming happens with framebits?

Thanks
