Please adhere to the following instructions strictly to create the COM driver.

To read digital input information.

1When reading digital input, set the desired channel to ON (1) and then read the target bit. Set the channel back to OFF (0) when the information has been read.

2Do not activate both Ch15 and Ch16 at the same time because this will cause an excessive current flow; which will result in a sudden temperature increase in the buffer IC and regulator IC.

Prolonged exposure to increased temperature will cause overheating in your buffer IC and regulator IC.
