SCLK
Serial Clock Input. Clocks data in and out of the serial interface.
(Duty cycle must be 40% to 60%.) See Table 3 for details on
programming the clock mode.

CS
Active-Low Chip Select Input. When
CS
is low, the serial interface
is enabled. When
CS
is high, DOUT is high impedance.

DIN
Serial Data Input. DIN data is latched into the serial interface on
the rising edge of SCLK.

DOUT
Serial Data Output. Data is clocked out on the falling edge of
SCLK. High impedance when
CS
is connected to V
