SUC16FS
Setup time, sixteenth negative SCLK edge after FS
low on which D0 is sampled before rising edge of FS.
Setup time, sixteenth positive SCLK edge (first
positive after D0 sampled) before NCS rising edge.
If FS is used instead of the sixteenth positive edge to
update the DAC, then the setup time is between the
FS rising edge and the NCS rising edge.
Pulse duration, SCLK high.
