1. Enable interrupt support only if input GPIO's are used. 1. Enable interrupt support only if input GPIO's are used.
2. All the INT GPIO's on the extenders must be connected to the one GPIO on AVR. Only PORTD4 - PORTD7 are acceptable! 2. All the INT GPIO's on the extenders must be connected to the one GPIO on AVR. Only PORTD0 - PORTD7 are acceptable!
3. The input GPIO's are always pullup to the power supply. 3. The input GPIO's are always pullup to the power supply.
