Timing chart
The video output from a single pixel is equal to 8 MCLK (master clock) pulses. The MSP (master start pulse) is a signal for setting the
integration time, so making the low (0 V) period of the MSP longer will extend the integration time. The MSP also functions as a signal
that triggers each control signal to perform frame scan. When the MSP goes from low (0 V) to high (5 V) , each control signal starts on
the falling edge of the MCLK and frame scan is performed during the high period of the MSP.
One frame scanning period [64 rows × 64 columns (including blank) × 8 MCLK]

*3: Integration time max.=10 ms
*4: If the sensor is driven with these timings set shorter than the Min. value, then the operation may delay by 1 MCLK pulse.
