The delay time from any FS signals to the corresponding FSD signals is m shift clocks with the value of m being the
numerical value of the data programmed into the FSD register. In the master mode with slaves, the same data word
programs the master and all slave devices; therefore, master to slave 1, slave 1 to slave 2, slave 2 to slave 3, etc., have
the same delay time.
