3.6.3.2 Measurement/Capture Trigger

The Measurement/Capture Trigger drop-down menu allows the device measurement and capture trigger to be switched between the INT Pin/Timer, Timer/Timer, Timer/INT Pin, and Timer/INT PinBy2 modes. This can only be selected when operating in oneshot (AGC) or oneshot mode. INT Pin/Timer has an input to trigger a measurement. Since the INT pin is used as input, there is no hardware interrupt to indicate the completion of measurement, so a timer is used to keep time from the trigger measurement and read out output registers. With a timer measurement, the next measurement is set by the timer and the INT Pin, INT PinBy2 (every second INT Pin) or the timer can indicate measurement completion to read out output registers.
