PRODUCTION DATA.
The START pin or the START command controls the conversions. If using commands to control conversions, keep the START pin low to avoid contention between the pin and commands. Commands take affect on the 32nd falling SCLK edge. See the Switching Characteristics table for details on conversion control timing.
The ADC has two conversion control operating modes: continuous-conversion mode and pulse-conversion mode. The continuous-conversion mode performs conversions indefinitely until the user stops the conversions. Pulse-conversion mode performs one conversion and then stops. The CONVRT (bit 4 of the MODE1 register) programs the mode.
