When the START pin is pulled high or the START command is issued, conversions continue indefinitely until the START pin is taken low or the STOP command is transmitted, as shown in Figure 34. When the START pin is pulled low or the STOP command is issued, the conversion in progress completes and the DRDY output transitions from high to low indicating that the latest data are available. Figure 35 and Table 6 illustrate the timing of where the START pin can be brought low or the STOP command can be sent relative to a completed conversion to halt further conversions. If the START pin is pulled low or if the STOP command is sent after the tDSHD time, then an additional conversion takes place and completes before further conversions are halted. To continuously run the converter without commands, tie the START pin high.
|tSDSU||Setup time; set the START pin low or send the STOP command before the DRDY falling edge to halt further conversions||16||tCLK|
|tDSHD||Delay time; set the START pin low or send the STOP command to complete the current conversion and halt further conversions||16||tCLK|
