PRODUCTION DATA.
Conversions are controlled by either the START pin or by the START command. If using commands to control conversions, keep the START pin low to avoid contentions between pin and commands. Commands take affect on the 16th falling SCLK edge (CRC mode disabled) or on the 32nd falling SCLK edge (CRC mode enabled). See Figure 4 for conversion-control timing details.
The ADC provides two conversion modes: continuous and pulse. The continuous-conversion mode performs conversions indefinitely until stopped by the user. Pulse-conversion mode performs one conversion and then stops. The conversion mode is programmed by the CONVRT bit (bit 4 of register MODE0).
