The following shows the timing charts when communication is performed with external
devices.
■ Basic operation
● Explanation of operations
(1) During each sampling cycle, the LEDs are lit up and exposure is started.
(2) After the end of exposure, measurement starts.
(3) After the end of measurement, the judgment results and binary data are output.
(4) After the judgment results and binary data are output, the analog output is
updated.
(5) After the judgment results and binary data are output, the GATE signal is turned
ON.
(6) The GATE output time after the GATE signal is turned ON, the GATE signal is
turned OFF.
