2. ENBL pin and INT pin clock pulse output
The INT pin outputs the fixed-cycle interrupt signal when the ENBL pin is "H". The INT pin is fixed to Nch open-drain
output = "L" or CMOS output = "H" when the ENBL pin is "L".
Duty ratio of the INT pin may change when the "H" and "L" of the ENBL pin changes. The example of the INT pin output
timing is shown below.
