Hi;
Because of customer carelessness, I used PCA9544A with the HW configuration of pull-down all the INT in/out pins to GND directly(because unused). And now there is no chance to modify. I note that there is a description which says ‘The interrupt inputs can be used as general-purpose inputs if the interrupt function is not required.’ I think this characteristic may solves my problem.
I want to know how to set the PCA9544A to let the INT input pins used as general IO port. Would you like to give me some supporting?
