The BUSY signal will remain ON while the measurement is being executed.
Performing Continuous Measurements
Continuous measurements are performed while the continuous measurement command is input from an
external device.
Immediately after a measurement is performed, the next measurement is performed.
This is repeated while a continuous measurement command is input with the IN0 to IN5 signals.
Note
This function can be used only when the input mode is set to Expanded Mode.
