Hello,
It's not immediately clear from the datasheet, but is it possible to configure the TCA9534 to trigger it's INT output based on more than one input state change?
I essentially mean using the I/O expander somewhat like an OR gate, where state changes on any of P0, P1, and P2 could all trigger the INT output.
Not sure if this is possible with this device, or with others in this family.
Thanks,
Jim
