Power-Down Enable. Must be high to allow software shutdown mode.
Load DAC Input (active low). Driving this asynchronous input low (level sensitive) transfers the contents
of each input latch to its respective DAC latch.
Clear DAC Input (active low). Driving CLR low asynchronously clears the input and DAC registers, and
sets all DAC outputs to zero.
Serial Data Output. Sinks and sources current. Data at DOUT can be clocked out on the rising or falling
edge of SCLK (Table 1).
Chip-Select Input (active low). Data is shifted in and out when CS is low. Programming commands are
executed when CS returns high.
Serial Clock Input. Data is clocked in on the rising edge and clocked out on the falling (default) or rising
edge (A0 = A1 = 1, see Table 1).
Serial Data Input. Data is clocked in on the rising edge of SCLK.
