The ADS124S0x offers two conversion modes: continuous conversion and single-shot conversion mode. Continuous-conversion mode converts indefinitely until stopped by the user. Single-shot conversion mode performs one conversion after the START/SYNC pin is taken high or after the START command is sent. Use the MODE bit in the data rate register (04h) to program the conversion mode. Figure 84 shows how the START/SYNC pin and the START command are used to control ADC conversions.
ADC conversions are controlled by the START/SYNC pin or by serial commands. For the device to start converting in continuous conversion or single-shot conversion mode, a START command must be sent or the START/SYNC pin must be taken high. If using commands to control conversions, keep the START/SYNC pin low to avoid possible contentions between the START/SYNC pin and commands.
Conversions can be synchronized to perform a conversion at a particular time. To synchronize the conversion with the START/SYNC pin, take the pin low. The rising edge of the START/SYNC pin starts a new conversion. Similarly, a conversion can be synchronized using the START command. If the device is in standby mode, issue a START command. If the device is in conversion mode, issue a STOP command followed by a START command. The STOP and START commands can be consecutive. A new conversion starts on the seventh SCLK falling edge of the START command.
