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.

Controlling Operation and Outputting Data with the Sensor's Standard Parallel Connection
When the single measurement
command bit (W0.00) turns
ON, the TRIG signal is turned
ON if the BUSY signal is OFF.
The TRIG signal is kept ON for
2 ms and then turned OFF.
When the BUSY signal turns OFF to
indicate that the measurement has been
finished, the judgement result is added
to the total count.
