Timing Chart for the Execution of Continuous Measurement Commands without Handshaking
Continuous execution is used to repeatedly execute measurements by starting the next measurement
operation (image input and measurement processing) as soon as one measurement operation (image input
and measurement processing) is completed.
Continuous measurements are started when the Start Continuous Measurements command is executed and
ended when the End Continuous Measurements command is executed.
The BUSY signal remains OFF during continuous measurement, but in this state the Sensor Controller can
receive the End Continuous Measurements command.
