Note: The internal timing circuit starts operating at the rise of CLK pulse immediately after ST pulse sets to low.
The integration time equals the high period of ST pulse plus 6 CLK cycles.
The output from 1st channel appears 14 clocks plus 100 ns after the falling edge of ST pulse.
The EOS pulse is output 39 ns after the falling edge of CLK pulse.
The output voltage after reading the last pixel (512 ch) is indefinite.
The integration time can be changed by changing the high-to-low ratio of ST pulses.
Start pulse setting example (for setting the start pulse cycle to a minimum and the integration time to a maximum)
Start pulse high period=515/f(CLK), Start pulse low period=15/f(CLK)
