Operating sequence
(1) Set the Gate terminal and CK terminal to “Low”.
(2) Select the desired sensitivity with the Range terminal.
(3) Set the Gate terminal from “Low” to “High”, to start integrating the light intensity.
(4) After the desired integration time (tg) has passed, set the Gate terminal from “High” to “Low” to end the light intensity integration.
(5) Measurement data is output from the Dout terminal by inputting 36 CK pulses to the CK terminal.
Note 1: A total of 36 CK pulses are required to read out 3-color measurement data. Red data is output by the first 12 pulses,
green data by the next 12 pulses, and blue data by the last 12 pulses. Measurement data is output from the LSB side.
Note 2: Measurement data changes at the CK pulse rising edge.
Note 3: Do not switch the Range terminal during integration time (tg).
