out to two downstream pairs, or channels. Any individual SCn/SDn channel or combination of channels can be

selected, determined by the contents of the programmable control register. Two interrupt inputs (INT0–INT1),

one for each of the downstream pairs, are provided. One interrupt output (INT) acts as an AND of the two

interrupt inputs.
