Simutanous is the key word. So in that respect it there should not be any issues, but it still confused as to why when I toggle the INT1 pin to interrupt the MPU that it never breaks out to go to do the ISR call. INT0 does every time, but INT1 does not.

You had the ???? > Pin 9 of the 924 is SDA/INT0/P1.3 So if it is dedicated to the I2C bus, it can not be used as an input for the INT0 falling edge trigger. That is why I used Pin 8 INT1/P1.4. I think this is what the ???? was for?

I didn't have to program the pins as bidirectional, input, output or push pull for INT0 to work, I'm wondering if I have to do it for INT1 to make it an input???

It doesn't mention anywhere that this needs to be done and the standalone tests didn't need it either. Which is why I'm scratching my head. If the standalone tests didn't work then I'd be like yeah, I'm doing something wrong, but that isn't he case here.

I used this example to do the standalones and its from a "known" source:

I changed the EX0 to EX1 and so forth and monitored the interrupt plugin, and they both worked the same way with some simple source in the ISR routine. I plug it back into my I2C receiver....nothing on INT1.

Any other thoughts Erik? Thanks
