I/O1~3 are identified by 3 values, and output according to the combinations shown in
the following table.
Judge the DC level of CINS1, the CINS2 terminal, and do the detection of the S input.

Note.
(1) VOUT is set to 2.1V, while CIN is set to 4.2V.
Be careful since the capacitor polarity may differ according to the comb filter bias.
(2) The case that a Y element is left by the Comb-filter character is presumed the condenser of CIN1, CIN2, and
there is it as 10µF.
You can use 0.01µF when a Y element isn't left in the croma output of Comb-filter.
